435090000 | Dinucleotide (e.g., NAD, etc.) | 8 |
20100151529 | ENGINEERED PHOSPHITE DEHYDROGENASE MUTANTS - Phosphite dehydrogenase mutant enzymes provide relaxed cofactor specificity, increased thermostability, increased activity, solubility, and expression over the wild-type enzyme. The mutant enzymes are useful for nicotinamide cofactor regeneration. | 06-17-2010 |
20120040403 | DIGUANYLATE CYCLASE METHOD OF PRODUCING THE SAME AND ITS USE IN THE MANUFACTURE OF CYCLIC-DI-GMP AND ANALOGUES THEREOF - Described is a new stand-alone diguanylate cyclase polypeptide having a GGDEF motif and a mutated I-site that does not bind c-di-GMP. We demonstrate that the production yield of c-di-GMP and analogues was significantly increased by mutation of a conserved residue in the putative regulatory I-site. | 02-16-2012 |
20130029378 | NOVEL ENZYME - The invention provides an isolated formate dehydrogenase (FDH) polypeptide specific for NADP | 01-31-2013 |
20130183716 | NOVEL GLUCOSE DEHYDROGENASE - The invention relates to a glucose dehydrogenase showing an NADP/NAD activity ratio, namely the value obtained by dividing the enzyme activity value obtained by using NADP as a coenzyme by the enzyme activity value obtained by using NAD as a coenzyme, of not lower than 300, to a gene coding therefor, and to a transformant harboring that gene. The enzyme of the invention is very high in NADP specificity and can be suitably used, for example, for NADPH production, for coenzyme regeneration in enzymatic reduction reactions, and in biosensors for glucose concentration measurements. | 07-18-2013 |
20130203118 | Whole-Cell Biocatalyst - The invention relates to a nucleic acid molecule comprising a section that encodes a signal peptide, a section that comprises a heterologous redox factor-regenerating polypeptide, an optional section that encodes a protease detection site, a section that encodes a transmembrane linker, and a section that encodes a transporter domain of an autotransporter or a variant thereof. The nucleic acid molecule enables the expression of redox factor-regenerating enzymes. | 08-08-2013 |
20150044723 | COFACTOR REGENERATION SYSTEM - The present invention relates to cofactor regeneration systems, components and uses thereof and methods for generating and regenerating cofactors. The cofactor regeneration system comprises a first electron transfer component selected from a polypeptide comprising a NADH:acceptor oxido-reductase or NADPH:acceptor oxido-reductase, a second electron transfer component selected from a hydrogenase moiety and/or non-biological nanoparticles and an electronically conducting surface. The first and second electron transfer components are immobilised on the electrically conducting surface, and the first and second electron transfer components do not occur together in nature as an enzyme complex. | 02-12-2015 |
20150044724 | PRACTICAL METHOD FOR ENZYMATICALLY SYNTHESIZING CYCLIC DI-GMP - A practical method for enzymatically synthesizing c-di-GMP with excellent productivity is provided. A diguanylate cyclase having physical and chemical characteristics (A) to (F): (A) catalytic action on reaction “2 GTP→c-di-GMP”; (B) a molecular weight of 19800±2000; (C) an optimum pH of 7.3 to 9.4; (D) an optimum temperature of 35 to 60° C.; (E) thermal stability as the remaining activity of 90% or higher after heated for 60 minutes under conditions of 50° C. and pH 7.8; and (F) the presence of GGDEF domain and the lack of amino acid sequence KXXD in the i-site. | 02-12-2015 |
20160036061 | Tethering of Cofactors on Graphene-like Materials - A family of customizable tethering molecules for tethering cofactors such as, but not necessarily limited to, nicotinamine adenine dinucleotide (NAD+/NADH, NAD(P)+/NAD(P)H) to substrates or structures formed from or including graphene-like materials is described. The tethered cofactor can then be used, for example, as biosensors employed for clinical diagnostic, food industry, medical drug development and environmental and military applications, as well as in reagentless biofuel cells for power generation. | 02-04-2016 |
