Engineering a Formate Dehydrogenase for NADPH Regeneration
2023年10月17日 · Nicotinamide adenine dinucleotide (NADH) and nicotinamide adenine dinucleotide phosphate (NADPH) constitute major hydrogen donors for oxidative/reductive bio-transformations. NAD (P)H regeneration systems coupled with formate dehydrogenases (FDHs) represent a dreamful method.
Classification and enzyme kinetics of formate dehydrogenases for ...
2019年11月15日 · We present a new sequence-based classification of FDHs and discuss how the individual FDH enzyme groups are suited for CO 2 reduction. We also examine reaction rates, efficiencies of different common electron donor principles, and …
Formate dehydrogenase, ubiquinone, and cytochrome
2020年2月6日 · Our results show that formate dehydrogenases (FDH), and especially FDH-O, are required for PGRP-induced production of H 2 O 2 and killing in E. coli, in addition to the previously identified...
Formate Dehydrogenase - an overview | ScienceDirect Topics
Formate dehydrogenases (FDH) constitute a diverse group of enzymes found in both eukaryotes and prokaryotes, which catalyze the formate oxidation to CO2. In contrast to most FDHs from aerobic bacteria, FDHs from anaerobes contain metal cofactors.
FDH/Hases-S-chain mediated electron redistributing in
2023年9月1日 · Electrochemical (LSV, I-t, DPV, EIS and EDC) and respiratory inhibition experiments clarified that the bio-FeS could greatly switch/redistribute electron transmembrane-transfer from intracellular to extracellular mainly via FDH/Hases-S-chain, as revealed by the significant increase of ipa-FDH/Hases /ipa-FC-Cyts and ipc-FDH/Hases /ipc-FC-Cyts ...
解锁甲酸脱氢酶的催化多样性:NADPH 再生的甲酰胺活性和不对 …
来自博伊丁假丝酵母的甲酸脱氢酶 (FDH)是一种经过充分研究和应用的酶,可用于各种反应中的 NADH 再生。 由于许多氧化还原酶需要 NADPH,因此创建了 FDH 突变体,其辅因子特异性转向 NADP +。 然而,在阐明氢化物供体的底物特异性方面所做的努力较少。 在这里,我们报道了FDH催化甲酰胺 (F)及其衍生物裂解成CO 2和胺,同时再生辅因子NADH和NADPH。 野生型 FDH 和 NADP +接受变体 FDH C23S/D195Q/Y196R/Q197N (FDH M5) 在 10% (v/v) F, N-甲基甲 …
