AB  - The distinguishing property of Sm protein associations is their high stability. In order to understand this property, we analyzed the interface non-covalent interactions and compared the properties of the Sm protein interfaces with those of a test set, Binding Interface Database (BID). The comparison revealed that the main differences between interfaces of Sm proteins and those of the BID set are the content of charged residues, hydrogen bonds, salt bridges, and conservation scores of interface residues. In Sm proteins, the interfaces have more hydrophobic and fewer charged residues than the surface, which is also the case for the BID test set and other proteins. However, in the interfaces, the content of charged residues in Sm proteins (26%) is substantially larger than that in the BID set (22%). Both interfaces of Sm proteins and of test set have a similar number of hydrophobic interactions per 100 angstrom(2). The interfaces of Sm proteins have substantially more hydrogen bonds than the interfaces in test set. The results show clearly that the interfaces of Sm proteins form more salt bridges compared with test set. On average, there are about 16 salt bridges per interface. The high conservation score of amino acids that are involved in non-covalent interactions in protein interfaces is an additional strong argument for their importance. The overriding conclusion from this study is that the non-covalent interactions in Sm protein interfaces considerably contribute to stability of higher order structures. (C) 2010 Elsevier Ltd.

AB  - Analysis of crystal structures from the Cambridge Structural Database (CSD) and high level ab initio calculations reveals that the water/aromatic parallel alignment interactions; where the water molecule or one of its 0 H bonds is parallel to the aromatic ring plane, can be significantly strong at large horizontal displacements. We found out that the strongest energies of the interactions are calculated for the water position with the large horizontal displacements, out of the aromatic ring and out of the C-H bond region. For calculated systems, normal distances were decreasing with increasing the horizontal displacement, in accord with the data found in crystal structures. The calculated energies of the interactions are significant, up to Delta E-CCSD(T)(limit) = -10.25 kJ/mol (at a horizontal displacement of 2.6 angstrom), and comparable with the energy of the slipped-parallel benzene/benzene dimer. Both dispersion and electrostatic components of the interaction energy are important. The calculated interaction energies reveal that also at long horizontal displacements of 3.5 angstrom, interaction is substantially strong, up to Delta E-CCSD(T(limit) = -623 kJ/mol. The data show the existence of the water/aromatic parallel alignment interactions in crystal structures and indicate their importance for various systems.

The comparison revealed that the main differences between the interfaces of Sm proteins and those of the BID set are the content of charged residues, the coordination numbers of the residues, knowledge-based pair potentials, and the conservation scores of hot spots. In Sm proteins, the interfaces have more hydrophobic and fewer charged residues than the surfaces, which is also the case for the BID test set and other proteins. However, in the interfaces, the content of charged residues in Sm proteins (26%) is substantially larger than that in the BID set (22%). Hot spots are residues that make up a small fraction of the interfaces, but they contribute most of the binding energy. These residues are critical to protein-protein interactions. Analyses of knowledge-based pair potentials of hot spot and non-hot spot residues in Sm proteins show that they are significantly different; their mean values are 31.5 and 11.3, respectively. In the BID set, this difference is smaller; in this case, the mean values for hot spot and non-hot spot residues are 20.7 and 12.4, respectively. Hence, the pair potentials of hot spots differ significantly for the Sm and BID data sets. In the interfaces of Sm proteins, the amino acids are tightly packed, and the coordination numbers are larger in Sm proteins than in the BID set for both hot spots and non-hot spots. At the same time, the coordination numbers are higher for hot spots; the average coordination number of the hot spot residues in Sm proteins is 7.7, while it is 6.1 for the non-hot spot residues. The difference in the calculated average conservation score for hot spots and non-hot spots in Sm proteins is significantly larger than it is in the BID set. In Sm proteins, the average conservation score for the hot spots is 7.4. Hot spots are surrounded by residues that are moderately conserved (5.9). The average conservation score for the other interface residues is 5.6. The conservation scores in the BID set do not show a significant distinction between hot and non-hot spots: the mean values for hot and non-hot spot residues are 5.5 and 5.2, respectively. These data show that structurally conserved residues and hot spots are significantly correlated in Sm proteins.

In most of the crystal structures, two terpyridyl complexes were oriented "head-to-tail" or "head-to-head", with "head-to-tail orientation" being most prevalent. The number of structures with other orientations was very small. Based on the analysis of interacting geometries, we classified overlaps of terpyridyl complexes into six types.

AB  - Evidence of chelate-chelate stacking interactions was obtained by analyzing crystal structures of square-planar transition-metal complexes from the Cambridge Structural Database. The analysis showed that chelate-chelate stacking interactions occur in a large number of the crystal structures of neutral square-planar complexes. We found 955 structures with 1866 chelate-chelate stacking interactions. In most of the structures, dictate rings are fused with other chelate rings or with organic aromatic rings; however, chelate chelate stacking interactions of isolated rings were also found. In order to describe the geometry of the chelate-chelate stacking interactions, several geometric parameters were analyzed. In most of the interactions, two chelate rings are in parallel or antiparallel orientation. The normal distances are similar to the distances of stacking interactions observed in other systems, while the offset of two interacting chelate rings can be different from that observed in other systems.

AB  - Catalytic oxygen atom transfer (OAT), which frequently employs molybdenum oxo species, is an important reaction for both nature and industry. The mechanistic details of oxygen atom transfer from Tp(R)MoO(2)(XPh) to PMe(3) were investigated for R = 3-iPr and 3-Me and X=O and S by density functional theory (DFT) calculations of the enthalpies, free energy with solvent corrections, and natural bond orbital (NBO) analysis. The mechanism for both systems proceeds via rate-determining attack of PMe(3) to form a stable intermediate with a bound OPMe(3) ligand. From this intermediate the reaction proceeds through a substitution involving loss of OPMe(3) and coordination of a single CH(3)CN solvent molecule. The solvent corrected free energy barriers of the rate-determining OAT step for the O and S systems were found to be energetically more favorable for the S systems by 6.2 and 2.2 kcal/mol (for the R=3-iPr and 3-Me, respectively). This lower energy barrier is the result of better stabilization by the SPh ligand of the Mo(IV) products and the transition states, which are the unexpectedly later and more product-like. Additional examination of the NBO analysis emphasizes the role of the local acidity of the Mo and by extension the character of the ligands. The decreased electronegativity and softer character of the S atom result in an increased covalent character in the Mo-X bond which leads to the stabilization of a later (and lower energy) transition state and the corresponding product of the S system relative to O system.

AB  - Fast time-resolved infrared spectroscopic measurements have allowed precise determination of the rates of activation of alkanes by Cp'Rh(CO) (Cp' = eta(5)-C5H5 or eta(5)-C5Me5). We have monitored the kinetics of C-H activation in solution at room temperature and determined how the change in rate of oxidative cleavage varies from methane to decane. The lifetime of CpRh(CO)(alkane) shows a nearly linear behavior with respect to the length of the alkane chain, whereas the related Cp*Rh(CO)(alkane) has clear oscillatory behavior upon changing the alkane. Coupled cluster and density functional theory calculations on these complexes, transition states, and intermediates provide the insight into the mechanism and barriers in order to develop a kinetic simulation of the experimental results. The observed behavior is a subtle interplay between the rates of activation and migration. Unexpectedly, the calculations predict that the most rapid process in these Cp'Rh (CO)(alkane) systems is the 1,3-migration along the alkane chain. The linear behavior in the observed lifetime of CpRh(CO)(alkane) results from a mechanism in which the next most rapid process is the activation of primary C-H bonds (-CH3 groups), while the third key step in this system is 1,2-migration with a slightly slower rate. The oscillatory behavior in the lifetime of Cp*Rh(CO)(alkane) with respect to the alkane's chain length follows from subtle interplay between more rapid migrations and less rapid primary C-H activation, with respect to CpRh(CO)(alkane), especially when the CH3 group is near a gauche turn. This interplay results in the activation being controlled by the percentage of alkane conformers.

AB  - Using the data from Protein Data Bank the correlations of primary and secondary structures of proteins were analyzed. The correlation values of the amino acids and the eight secondary structure types were calculated, where the position of the amino acid and the position in sequence with the particular secondary structure differ at most 25. The diagrams describing these results indicate that correlations are significant at distances between -9 and 10. The results show that the substituents on C beta or C gamma atoms of amino acid play major role in their preference for particular secondary structure at the same position in the sequence, while the polarity of amino acid has significant influence on alpha-helices and strands at some distance in the sequence. The diagrams corresponding to polar amino acids are noticeably asymmetric. The diagrams point out the exchangeability of residues in the proteins; the amino acids with similar diagrams have similar local folding requirements.

AB  - A new, highly sensitive and simple kinetic method for the determination of thyroxine was proposed. The method was based on the catalytic effect of thyroxine on the oxidation of As(III) by Mn(III) metaphosphate. The kinetics of the reaction was studied in the presence of orthophosphoric acid. The reaction rate was followed spectrophotometrically at 516 nm. It was established that orthophosphoric acid increased the reaction rate and that the extent of the non-catalytic reaction was extremely small. A kinetic equation was postulated and the apparent rate constant was calculated. The dependence of the reaction rate on temperature was investigated and the energy of activation and other kinetic parameters were determined. Thyroxine was determined under the optimal experimental conditions in the range 7.0 x 10(-9) to 3.0 x 10(-8) mol L-1 with a relative standard deviation up to 6.7% and a detection limit of 2.7 x 10(-9) mol L-1. In the presence of 0.08 mol L-1 chloride, the detection limit decreased to 6.6 x 10(-10) mol L-1. The proposed method was applied for the determination of thyroxine in tablets. The accuracy of the method was evaluated by comparison with the HPLC method. (C) 2007 Elsevier B.V. All rights reserved.

AB  - Our previous experiences with incorporation of polyoxometalates (POMs) ill different substrates have been very successful, because new nanocomposites with better conductive, catalytical and biochemical characteristics have been obtained. The results of intercalation of different mass% of ammonium decavanadate (ADV) in Al-pillared interlayered clays (Al-PILCs) are presented. The Al-PILCs were prepared using natural raw material, bentonite, containing a high percentage of montmorillonite (MM). Synthesis of ADV has been described in a previous paper. The structure of ADV hexahydrate was determined at low temperature, 100 K. A kappa refinement was performed to estimate the atomic charges. A sol-gel procedure was applied to obtain Al-PILCs composite intercalated with ADV hexahydrate (from 2 to 5 mass% of ADV). Structure and morphological properties of the new material, a nanocomposite of Al-PILCs-ADV, were investigated by X-ray powder diffraction (XRPD) and atomic force microscopy (AFM). To understand better how ADV is incorporated in the MM substrate, specific surface areas, pore structures and pore distributions were determined. Electrical and dielectric properties of the new materials were investigated by thermally stimulated depolarization currents (TSDCs) and broadband dielectric relaxation spectroscopy (DRS). The electrical conductivity of the nanocomposite was found to increase, in relation to MM, by intercalating with a small amount of ADV. (C) 2008 Published by Elsevier Ltd.

AB  - Fast time-resolved infrared (TRIR) experiments and density functional (DFT) calculations have been used to elucidate the complete reaction mechanism between alkanes and photolytically activated hydridotris(pyrazoly-1-yl)boratodicarbonylrhodium. TRIR spectra were obtained after photolysis of Rh(TP4-tBu-3,5-Me)(CO)(2) in n-heptane, n-decane, and cyclohexane and of Rh(Tp(3,5-Me))(CO)(2) in n-heptane and cyclohexane. Initial photolysis produces a coordinatively unsaturated, 16-electron monocarbonyl species that vibrationally relaxes to an intermediate with v(CO) of 1971 cm(-1) in n-heptane solution (species A). DFT calculations on Rh(Tp(3,5-Me))(CO)-RH (RH = C2H6, C6H12) suggest that A is the triplet state of a five-coordinate, square-pyramidal Rh(k(3) -Tp(3,5-Me))(CO)-RH, in which the alkane is weakly bound. Within the first 2 ns, a new transient grew in at 1993 cm(-1) (species B). The calculations show that the observed species B is the singlet state of a four-coordinate Rh(K-2-Tp(3,5-Me))(CO)(RH), in which the alkane is strongly bound and one pyrazolyl ring is rotated, decoordinating one N. The transient due to B grew at the same rate as A partially decayed. However, A did not decay completely, but persisted in equilibrium with B throughout the time up to 2500 ps. The v(CO) bands due to A and B decayed at the same rate as a band at 2026 cm(-1) grew in (tau ca. 29 ns, n-heptane). The latter band can be readily assigned to the final alkyl hydride products, Rh(K-3-Tp(4-tBu-3,5-Me))(CO)R(H) and Rh(K-3-Tp(3,5-Me))(CO)R(H) (species D). The experimental data do not allow the elucidation of which of the two alkane complexes, A or B, is C-H activating, or whether both of the complexes react to form the final product. The calculations suggest that a third intermediate (species Q is the C-H activating species, that is, the final product D is formed from C and not directly from either A or B. Species C is nominally a five-coordinate, square-pyramidal Rh(K-21/2-T-p3,T-5-Me)(CO)(RH) complex with a strongly bound alkane and one pyrazolyl partially decoordinated, but occupying the apical position of the square pyramid. Intermediate C is unobserved, as the calculations predict it possesses the same CO stretching frequency as the parent dicarbonyl. The unobserved species is predicted to lie on the reaction path between A and B and to be in rapid equilibrium with the four-coordinate species B.

AB  - The correlation between the primary and secondary structures of proteins was analysed using a large data set from the Protein Data Bank. Clear preferences of amino acids towards certain secondary structures classify amino acids into four groups: alpha-helix preferrers, strand preferrers, turn and bend preferrers, and His and Cys (the latter two amino acids show no clear preference for any secondary structure). Amino acids in the same group have similar structural characteristics at their C beta and C gamma atoms that predicts their preference for a particular secondary structure. All alpha-helix preferrers have neither polar heteroatoms on C beta and C gamma atoms, nor branching or aromatic group on the C beta atom. All strand preferrers have aromatic groups or branching groups on the C beta atom. All turn and bend preferrers have a polar heteroatom on the C beta or C gamma atoms or do not have a C beta atom at all. These new rules could be helpful in making predictions about non-natural amino acids.

AB  - Searching structures of porphyrin-containing proteins from the Protein Data Bank revealed that the pi system of every porphyrin ring is involved in XH/pi interactions, with most of the porphyrins having several interactions. Both five-membered pyrrole rings and six-membered chelate rings are involved in XH/pi interactions; the number of interactions with five-membered rings is larger than the number of interactions with six-membered rings. We found interactions with C-H and N-H groups as hydrogen-atom donors; however, the number of CH/pi interactions is much larger than the number of NH/pi interactions. The amino acids involved in the interactions show a high conservation score. Our results that every porphyrin is involved in XH/pi interactions and that amino acids involved in these interactions are highly conserved demonstrate that XH/pi interactions play an important role in porphyrin-protein stability.

AB  - Three closely related [MoO(2)(L)(ML)] complexes, where L is the 2-hydroxy-1-naphthaldehyde-S-methylisothiosemicarbazone ligand, and ML is EtOH (I), Py (II) and DMSO (III), were synthesized, characterized by NMR and IR spectra, and their X-ray crystal structures were determined. The crystal structure properties of these three closely related complexes were compared. Two cis-Mo-O bond lengths were almost the same in the crystal structure of complexes II and III, while in complex I a significant difference between the two cis-Mo-O bond lengths was observed. At the same time, the geometry of L ligand in complex I is different, compared to II and III. DFT calculations on the isolated molecule I, as well as geometrical analysis of the complexes indicate that intramolecular interactions are not responsible for these structural differences. On the other hand, the pattern of intermolecular contacts in the crystal structure of I differs from those observed in II and III. Analyses indicate that differences in cis-Mo-O bond lengths and in the geometry of ligand L could be related to intermolecular interactions. These results suggest the possibility that in enzymes oxotransferases or in their model systems, the Mo-O bond length could be designed by the interactions of chelate ligands with the surroundings.

At the same time, the geometry of L ligand in complex I is different, compared to II and III. DFT calculations on the isolated molecule I, as well as geometrical analysis of the complexes indicate that intramolecular interactions are not responsible for these structural differences. On the other hand, the pattern of intermolecular contacts in the crystal structure of I differs from those observed in II and III. Analyses indicate that differences in cis-Mo-O bond lengths and in the geometry of ligand L could be related to intermolecular interactions. These results suggest the possibility that in enzymes oxotransferases or in their model systems, the Mo-O bond length could be designed by the interactions of chelate ligands with the surroundings.

AB  - The crystal structures of square-planar transition-metal complexes from the Cambridge Structural Database (CSD) with close contacts between planar chelate rings and aryl rings containing six carbon atoms (C-6- aryl) were analyzed. Most of the chelate rings in these structures are fused with aromatic or other pi-delocalized chelate rings. The results show that planar chelate rings can be involved in stacking and CH-pi interactions with organic aryl rings. However, the number of stacking interactions is a few times larger than the number of CH-pi interactions. The analysis also shows that in almost all cases CH-pi interactions are formed only when stacking interactions are prevented by voluminous substituents. Hence, between planar chelate rings and C-6- aryl rings stacking interactions are preferred to CH-pi interactions.

AB  - The reactivity of a set of prototypical (eta(6)-arene)tricarbonylchromium complexes bearing amino, oxazolyl, and pyridyl ancillary ligands versus [Cp*RhCl2](2) and [Cp*IrCl2](2) has been investigated. Successful cyclometalation reactions were achieved essentially in the presence of hydrated sodium acetate with planar-prochiral 2-phenylpyridine and 3-methyl-2-phenylpyridine complexes with yields ranging from 60% to 92%. The most salient feature of the reported reactions is their stereoselectivity, as the only diastereomers to be produced are those with the Rh- and Ir-bound chloro ligand located trans with respect to the Cr(CO)(3). According to X-ray diffraction analyses, a relative rac-(pR,T-4-S) configuration may be assigned to the complexes: the Cp* ligand sits unexpectedly syn with respect to the tricarbonylmetal moiety. Introduction of the Cr(CO)(3) moiety by treatment of cycloiridated 2-phenylpyridine with tricarbonyl(eta(6)-naphthalene)chromium resulted in a unique diastereomer of the same relative configuration. Quantum calculations using the density functional theory were carried out on models of syn and trans-chloro isomers. Owing to strong electrostatic repulsion between the chloro ligand and the Cr(CO)(3) moiety, the syn-chloro isomers were found less stable by 7-8 kcal/mol than the trans counterparts, suggesting that cyclorhodation and cycloiridation reactions are thermodynamically controlled.

AB  - The aromaticity of the chelate rings of acetylacetonato (acac) and o-benzoquinonediimine (bqdi) ligands was investigated theoretically by calculating nucleus-independent chemical shifts (NICS). The calculations were done for the complexes with various metals and various other ligands. The results show that acac chelate rings in none of the complexes satisfy this magnetic criterion for aromaticity. According to the results for bqdi chelate rings, there is only the Ru2+-bqdi chelate ring with large negative NICS values, indicating possible aromaticity by magnetic criterion.

AB  - CH/pi interactions between the coordinated acetylacetonato ligand and phenyl rings were analyzed in the crystal structures from the Cambridge Structural Database and by quantum chemical calculations. The acetylacetonato ligand may engage in two types of interactions: it can be hydrogen atom donor or acceptor. The analysis of crystal structures and calculations show that interactions with the acetylacetonato ligand acting as hydrogen atom donor depend on the metal in an acetylacetonato chelate ring; the chelate rings with soft metals make stronger interactions. The same trend was not observed in the interactions where the acetylacetonato chelate ring acts as the hydrogen atom acceptor.

AB  - The calculations have been done for CH/pi interaction with pi-system of Ni(II)-acetylacetonato chelate ring. The results show that there is an attractive electrostatic interaction, while dispersion component is a major source of attractive interacting energies. The interaction was compared with CH/pi, interaction between two benzene rings. The comparison shows that two interactions are quite similar, enabling to estimate the energy of CH/pi interaction with pi-system of Ni(II)-acetylacetonato chelate ring to be about 10.5 kJ/mol. The results indicate that CH/pi interactions of chelate ring in various molecular systems can be as important as CH/pi interactions of phenyl ring. (c) 2006 Elsevier B.V. All rights reserved.
