AB  - Saccharomyces cerevisiae, known as bakers’ yeast, is one of the most utilized yeasts in industry. Several enzymes that are naturally produced by yeast, such as invertase and catalase, combined with heterologously expressed glucose oxidase (GOx), represent the enzyme machinery for fructose and gluconic acid production. Therefore, we have used yeast cell walls with expressed glucose oxidase as a platform for crosslinking with invertase and catalase to create biocatalyst cells for the high yield sucrose conversion. Using 5% (w/v) suspension of cross-linked yeast cell walls in 0.15 M sucrose solution, 1.86 g L−1 h−1 of gluconic acid has been obtained using wt-GOx, while mutant A2-GOx produced 2.91 g L−1 h−1 of gluconic acid. Increasing the concentration of modified yeast cells walls to 10% (w/v) we were able to obtain almost 100% conversion of glucose to gluconic acid using A2-GOx in the first cycle. Reusing the modified cells walls in three consecutive cycles, conversion dropped to approximately 70% using A2-GOx and 40% using wt-GOx.

AB  - Chitinases are glycosyl hydrolases, that cleave the β-1,4 linkage between N-acetyl glucosamines present in chitin chains. Chitin is the second most abundant polysaccharide on Earth after cellulose, and it is produced in the exoskeleton of crustaceans and insects, and in some parts of the cell walls of fungi. Enzymatic development and the extraction of superior derivatives from chitin wastes – such as chitooligosaccharides with vast importance in the medi­cal and biofuels industry – lead to the necessity of creating chitinases using dif­ferent strains of organisms. In this paper, the chiA gene from the Bacillus lich­eniformis DSM8785 encoding chitinase A (ChiA) with C-terminal hexahis­tid­ine tag was cloned and expressed in the extracellular expression system pYES2 from Saccharomyces cerevisiae INVSc1 as a hyperglycosylated enzyme. The production of recombinant ChiA was successfully confirmed by dot blotting, using anti-His antibodies. The optimal time of expression was identified to be 24 h when galactose was added only at the beginning of fermentation, the chit­in­ase activity starting to decrease after this threshold. Nevertheless, in another experiment, when galactose was added every 24 h for 72 h, the expression con­tinued for the entire period. The purified enzyme was detected, using sodium dodecyl sulphate–polyacrylamide gel electrophoresis (SDS-PAGE), as a het­ero­geneous diffuse band between 80 and 180 kDa. The molecular mass of the same ChiA enzyme expressed in Pichia pastoris KM71H and Escherichia coli BL21 (DE3) was compared using SDS-PAGE with ChiA expressed in S. cere­visiae INVSc1. The activity of ChiA was determined using the fluorogenic substrate, 4-methylumbelliferyl β-d-N,N,N-triacetylchitotrioside (4MUTC). Using a bioinformatics simulation, the number of the glycolsylation sites of the ChiA gene sequence and the proximity of these sites to the alpha factor sequ­ence were hypothesized to be a possible reason for which ChiA enzyme was internally expressed.

AB  - Production of soluble cellobiose dehydrogenase (CDH) mutant proteins previously evolved on the surface of S. cerevisiae yeast cells was established for use in biosensors and biofuel cells. For this purpose, mutant cdh genes tm (D20N, A64T, V592M), H5 (D20N, V22A, A64T, V592M) and H9 (D20N, A64T, T84A, A261P, V592M, E674G, N715S) were cloned to pPICZα plasmid and transformed into Pichia pastoris KM71H strain for high expression in a soluble form and kinetic characterization. After 6 days of expression under methanol induction, the CDHs were purified by ultrafiltration, ion- -exchange chromatography and gel filtration. Sodium dodecyl sulfate electrophoresis confirmed the purity and presence of a single protein band at a molecular weight of 100 kDa. Kinetic characterization showed that the H5 mutant had the highest catalytic constant of 43.5 s-1 for lactose, while the mutant H9 showed the highest specificity constant for lactose of 132 mM-1 s-1. All three mutant proteins did not change the pH optimum that was between 4.5 and 5.5. Compared to the previously obtained wild types and mutants of CDH from Phanerochaete chrysosporium, the variants reported in this article had higher activity and specificity that together with high protein expression rate in P. pastoris, makes them good candidates for use in biotechnology for lactobionic acid production and biosensor manufacture.

После 6 дана експресије подиндукцијом метанолом, мутанти су пречишћени ултрафилтрацијом, јоноизмењивачкомхроматографијом и гел-филтрацијом. SDS електрофореза је потврдила чистоћу уз присуствоједне протеинске траке молекулскe масe од 100 kDa. Кинетичка карактеризација је показалада H5 мутирани протеин поседује највећу каталитичку константу од 43,5 s-1 за лактозу, докје H9 имао највећу константу специфичности за лактозу од 132 mM-1 s-1. Сва три мутиранапротеина су имала неизмењен pH оптимум који је био у опсегу од 4,5 до 5,5. У поређењу сапретходно добијеним природним и мутантним облицима CDH протеина из Phanerochaetechrysosporium, облици приказани у овом раду имају већу активност и специфичност, што их,повезано са високом експресијом протеина у P.

AB  - Cellobiose dehydrogenase (CDH) can be used in industry for lactobionic acid production, as a part of biosensors for disaccharides and in wound healing. In fungi it is involved in lignocellulose degradation. CDH gene from Phanerochaete chrysosporium has been cloned in pYES2 plasmid for extracellular expression and protein engineering in yeast Saccharomyces cerevisiae InvSC1 for the first time. A CDH gene library was generated using error-prone PCR and screened by spectrophotometric enzymatic assay based on 2,6-dichloroindophenol reduction detection in microtiter plates. Several mutants with increased activity and specificity towards lactose and cellobiose were found, purified and characterized in detail. Recombinant CDH enzymes showed a broad molecular weight between 120 and 150 KDa due to hyper-glycosylation and the best S137 N mutant showed 2.2 times increased k cat and 1.5 and 2 times increased specificity constant for lactose and cellobiose compared to the wild type enzyme. pH optimum of mutants was not changed while thermostability of selected mutants improved and S137 N mutant retained 30% of it's original activity after 15 min at 70 °C compared to 10% of activity that the wild type enzyme retained. Mutants M65S and S137 N showed also 1.6 and 1.5 times increased productivity of hydrogen peroxide in the presence of 30 mM lactose compared to the wild type.

AB  - Cellobiose dehydrogenase (CDH) from Phanerochaete chrysosporium can be used in lactobionic acid production, biosensor for lactose, biofuel cells, lignocellulose degradation, and wound-healing applications. To make it a better biocatalyst, CDH with higher activity in an immobilized form is desirable. For this purpose, CDH was expressed for the first time on the surface of S. cerevisiae EBY100 cells in an active form as a triple mutant tmCDH (D20N, A64T, V592M) and evolved further for higher activity using resazurin-based fluorescent assay. In order to decrease blank reaction of resazurin with yeast cells and to have linear correlation between enzyme activity on the cell surface and fluorescence signal, the assay was optimized with respect to resazurin concentration (0.1 mM), substrate concentration (10mMlactose and 0.08mMcellobiose), and pH (6.0). Using optimized assay an error prone PCR gene library of tmCDH was screened. Two mutants with 5 (H5) and 7 mutations (H9) were found having two times higher activity than the parent tmCDH enzyme that already had improved activity compared to wild type CDH whose activity could not be detected on the surface of yeast cells.

AB  - Phenol and amino groups were introduced into alginate to different degrees via oxidation with 2.5, 5, 10, 15 and 20 mol% of periodate and reductive amination by tyramine. Modification of alginate with tyramine was confirmed by FTIR spectroscopy and UV-VIS spectroscopy, while concentration of phenol and ionizable groups was determined using absorbance at 275 nm and acid-base titration. All tyramine-alginates were able to form hydrogels after cross-linking with horse radish peroxidase (HRP) and hydrogen peroxide. Tyramine-alginates oxidized with up to 10 mol% of periodate were also capable of forming hydrogels with calcium ions. Tyramine-alginates were tested for HRP immobilization within micro-beads obtained by peroxidase catalyzed droplet polymerization using internal delivery of hydrogen peroxide via glucose oxidase and glucose. Highest activity of immobilized peroxidase was obtained with 20% (w/v) tyramine-alginate obtained via 20 mol% periodate oxidation. Immobilized enzyme was not leaking from the micro-beads and was further kinetically characterized for pyrogallol oxidation. Km for pyrogallol was increased after immobilization from 1.93 mM for soluble HRP to 734 mM for immobilized HRP. The optimum pH was also increased from pH 7.0 to 8.0. Temperature and organic solvent stability improved significantly after immobilization, so that half-life at 70 degrees C increased around four times, while half-life in 80% (v/v) dioxane increased 22 times. After repeated use of 6 times in batch reactor for pyrogallol oxidation immobilized HRP retained 45% of original activity.

AB  - Aspergillus niger glucose oxidase (GOx) genes for wild-type (GenBank accession no. X16061, swiss-Prot; P13006) and M12 mutant (N2Y, K13E, T30 V, I94 V, K152R) were cloned into pPICZ alpha A vector for expression in Pichia pastoris KM71H strain. The highest expression level of 17.5 U/mL of fermentation media was obtained in 0.5 % (v/v) methanol after 9 days of fermentation. The recombinant GOx was purified by cross-flow ultrafiltration using membranes of 30 kDa molecular cutoff and DEAE ion-exchange chromatography at pH 6.0. Purified wt GOx had k (cat) of 189.4 s(-1) and K (m) of 28.26 mM while M12 GOx had k (cat) of 352.0 s(-1) and K (m) of 13.33 mM for glucose at pH 5.5. Specificity constants k (cat)/K (m) of wt (6.70 mM(-1) s(-1)) and M12 GOx (26.7 mM(-1) s(-1)) expressed in P. pastoris KM71H were around three times higher than for the same enzymes previously expressed in Saccharomyces cerevisiae InvSc1 strain. The pH optimum and sugar specificity of M12 mutant of GOx remained similar to the wild-type form of the enzyme, while thermostability was slightly decreased. M12 GOx expressed in P. pastoris showed three times higher activity compared to the wt GOx toward redox mediators like N,N-dimethyl-nitroso-aniline used for glucose strips manufacturing. M12 mutant of GOx produced in P. pastoris KM71H could be useful for manufacturing of glucose biosensors and biofuel cells.

The pH optimum and sugar specificity of M12 mutant of GOx remained similar to the wild-type form of the enzyme, while thermostability was slightly decreased. M12 GOx expressed in P. pastoris showed three times higher activity compared to the wt GOx toward redox mediators like N,N-dimethyl-nitroso-aniline used for glucose strips manufacturing. M12 mutant of GOx produced in P. pastoris KM71H could be useful for manufacturing of glucose biosensors and biofuel cells.",

AB  - Glucose oxidase (GOx) catalyzes the oxidation of glucose to form gluconic acid and hydrogen peroxide, a reaction with important applications in food preservation, the manufacture of cosmetics and pharmaceuticals, and the development of glucose monitoring devices and biofuel cells. We expressed Aspergillus niger wild type GOx and the B11 mutant, which has twice the activity of the wild type enzyme at pH 5.5, as C-terminal fusions with the Saccharomyces cerevisiae Aga2 protein, allowing the fusion proteins to be displayed on the surface of yeast EBY100 cells. After expression, we extracted the proteins from the yeast cell wall and purified them by ion-exchange chromatography and ultrafiltration. This produced a broad 100-140 kDa band by denaturing SDS-PAGE and a high-molecular-weight band by native PAGE corresponding to the activity band revealed by zymography. The wild type and B11 fusion proteins had k(cat) values of 33.3 and 61.3 s(-1) and K-m values for glucose of 33.4 and 27.9 mM, respectively. The pH optimum for both enzymes was 5.0. The kinetic properties of the fusion proteins displayed the same ratio as their native counterparts, confirming that yeast surface display is suitable for the high-throughput directed evolution of GOx using flow cytometry for selection. Aga2-GOx fusion proteins in the yeast cell wall could also be used as immobilized catalysts for the production of gluconic acid.

AB  - This overview summarizes the application of enzymes in the manufacture and design of biofuel cells and biosensors. The emphasis will be put on the protein engineering techniques used for improving the properties of enzymes such as nanobiocatalysts, e.g. immobilization orientation, stability, activity and efficiency of electron transfer between immobilized enzymes and electrodes. Some possible applications in the military and some future designs of these electric devices will be discussed as well.
AB  - U ovom preglednom članku je sumirana primena enzima u proizvodnji i dizajnu biogorivnih ćelija i biosenzora. Naglasak u pregledu literature je stavljen na tehnike proteinskog inžinjeringa, koje se koriste za poboljšanje osobina enzima u nanobiokatalizatorima kao što su orijentacija kod imobilizacije, stabilnost, aktivnost i efikasnost transfera elektrona između imobilizovanog enzima i elektrode. Na kraju pregleda je dato nekoliko primera moguće primene u vojsci. Nanobiokatalizatori su biokatalizatori u obliku enzima ili ćelija imobilizovani na nanomaterijalima. Koriste se kao sastavni elementi gorivnih ćelija u vidu imobilizovanih oksidoreduktaza na elektrodama. Na anodi se uz pomoć enzima oksiduju hemijska jedinjenja i elektroni predaju elektrodi, dok se na katodi elektroni uz pomoć druge oksidoreduktaze prebacuju sa elektrode na vodu ili kiseonik. Enzimi koji se koriste na anodi su glukoza oksidaza, formaldehid dehidrogenaza, alkohol dehidrogenaza i druge oksidaze šećera. Na katodi se uglavnom koriste lakaze, bilirubin oksidaza, peroksidaze i citohrom c oksidaza. Zahvaljujući razvoju nanotehnologije razvijaju se i minijaturne biogorivne ćelije koje proizvode električnu energiju za implantirane medicinske uređaje (insulinske pumpe, pejsmejkere, biosenzore) koristeći glukozu i kiseonik iz ljudske krvi. Biosenzori predstavljaju uređaje koji se sastoje iz biološke komponente, transducera i električne komponente. Oni pretvaraju koncen traciju hemijske supstance u električni signal i koriste se za analitiku. Kao biološka komponenta se mogu koristiti enzimi, monoklonska antitela, nukleinske kiseline i lipidi. Enzimska logička kola predstavljaju kombinaciju različitih biosenzora (enzimskih reakcija) koji mere nekoliko ulaznih parametara i na osnovu njih daju odgovarajući izlazni signal. Koristeći znanja kompjuterske tehnologije enzimskim logičkim kolima mogu se simulirati AND, OR, XOR, NOR, NAND, INHIB i XNOR logička kola. Za poboljšanje osobina biokatalizatora u cilju efikasnije primene u bioelektrokatalizi koriste se tehnike proteinskog inžinjeringa kao što su racionalni dizajn i dirigovana evolucija. Dirigovana evolucija koristi iterativne korake mutiranja i selekcije, kako bi biokatalizator evoluirao u pravcu koji nam je potreban. Najsporiji stupanj u ovoj tehnologiji predstavlja 'skrining', te se u novije vreme pomoću protočne citometrije i mikrofluidike pokušavaju razviti nove metode visoko propusnog skrininga. U literaturi opisani primeri dirigovane evolucije glukoza oksidaze, glukoza dehidrogenaze, formaldehid dehidrogenaze, laktat dehidrogenaze, peroksidaze i lakaze. Kombinacijom enzimskih logičkih kola i mikrofluidne tehnologije se pokušavaju napraviti laboratorije na čipu koje bi omogućile kontinuirano praćenje zdravstvenog stanja vojnika na bojnom polju i u slučaju šoka (ranjavanja) primenu odgovarajuće terapije u toku prvih 30 minuta od povrede. To bi obezbedilo veći stepen preživljavanja vojnika u ratu. Takođe upotrebom enzimskih logičkih kola i antitela moguće je postići uskladištenje i šifrovanje informacija, kao i zaštitu lozinkom, odgovarajućih elektronskih uređaja kao što su biogorivne ćelije Razvoj nanotehnologije, proteinskog inžinjeringa i molekularnog računarstva otvara vrata novim mogućnostima u proizvodnji i dizajnu biogorivnih ćelija i bisenzorskih sistema, kao i u skladištenju i zaštiti informacija.
