New potentiometric sensor for copper determination in waste waters based on a new type of modified GC electrode
(Analytical and Bioanalytical Chemistry, 2012)
The potentiometrical analysis of Cu2+ using Nafion- modified electrode with Cu complex with DPABA (Methyl 3,5-bis{bis-[(pyridin-2-yl)methyl]amino}methyl)benzoate) incorporated, is described. Parameters and conditions such ...
In vivo self-hydroxylation of an iron-substituted manganese-dependent extradiol cleaving catechol dioxygenase
(Springer, New York, 2011)
The homoprotocatechuate 2,3-dioxygenase from Arthrobacter globiformis (MndD) catalyzes the oxidative ring cleavage reaction of its catechol substrate in an extradiol fashion. Although this reactivity is more typically ...
Synthesis of thiophosphoramidates in water: Click chemistry for phosphates
(Royal Soc Chemistry, Cambridge, 2011)
An aqueous method for the preparation of N,S-dialkyl thiophosphoramidates is reported. Thiophosphorylation of alkylamines was performed using SPCl3 in aqueous reaction media, and the resulting thiophosphoramidate-S-anions ...
Geometries of stacking interactions between phenanthroline ligands in crystal structures of square-planar metal complexes
(Springer, New York, 2011)
Stacking interactions of phenanthroline square-planar complexes in crystal structures were studied by analyzing data from the Cambridge Structural Database. In most of the crystal structures, two phenanthroline complexes ...
Production and properties of the highly efficient raw starch digesting alpha-amylase from a Bacillus licheniformis ATCC 9945a
(Elsevier Science Sa, Lausanne, 2011)
Highly efficient raw starch digesting alpha-amylase was produced after 24 h of batch fermentation of Bacillus licheniformis ATCC 9945a in laboratory bioreactor at 37 degrees C. The enzyme was purified by gel filtration ...
Bacterial dioxygenase- and monooxygenase-catalysed sulfoxidation of benzo[b]thiophenes
(Royal Soc Chemistry, Cambridge, 2012)
Asymmetric heteroatom oxidation of benzo[b]thiophenes to yield the corresponding sulfoxides was catalysed by toluene dioxygenase (TDO), naphthalene dioxygenase (NDO) and styrene monooxygenase (SMO) enzymes present in P. ...
Electrochemical Determination of Natural Drug Colchicine in Pharmaceuticals and Human Serum Sample and its Interaction with DNA
(Wiley-V C H Verlag Gmbh, Weinheim, 2017)
Colchicine (COLC) is a natural toxic product and secondary metabolite most commonly used to treat gout. In this study, its electrochemical behavior and determination was investigated by employing modification-free boron-doped ...
Electrochemical oxidation of phenanthrenequinone dioxime and its quantification using sensing at boron doped diamond electrode
(Elsevier Science Sa, Lausanne, 2016)
Nowadays, there is small number of analytical procedures for the quantification of the phenanthrene and its derivatives, quinones and quinonedioximes. In recent years, different studies shows that potential application of ...
Authentication of Turkish propolis through HPTLC fingerprints combined with multivariate analysis and palynological data and their comparative antioxidant activity
(Elsevier Science Bv, Amsterdam, 2018)
Propolis is a honeycomb product having very diverse chemical composition and possessing a broad spectrum of biological activities. This study comprehensively evaluated the phenolic profile of Turkish propolis by using a ...
The effect of polyphosphate kinase gene deletion on polyhydroxyalkanoate accumulation and carbon metabolism in Pseudomonas putida KT2440
(Wiley-Blackwell, Hoboken, 2013)
The primary enzyme involved in polyphosphate (polyP) synthesis, polyP kinase (ppk), has been deleted in Pseudomonas putidaKT2440. This has resulted in a threefold to sixfold reduction in polyhydroxyalkanoate (PHA) accumulation ...
