Abstract: Desulfovibrio fructosovorans, a sulfate‐reducing bacterium, possesses six gene clusters encoding six hydrogenases catalyzing the reversible oxidation of H2 into protons and electrons. Among them, Hnd is an electron‐bifurcating hydrogenase, coupling the exergonic reduction of NAD+… read more here.

DOI: 10.3389/fmicb.2022.946711
Abstract: Microorganisms utilize electron bifurcating enzymes in metabolic pathways to carry out thermodynamically unfavorable reactions. Bifurcating FeFe-hydrogenases (HydABC) reversibly oxidize NADH (E′∼−280 mV, under physiological conditions) and reduce protons to H2 gas (E°′−414 mV) by coupling… read more here.

DOI: 10.3389/fmicb.2023.1139276
Abstract: The tetrameric cytoplasmic FeFe hydrogenase Hnd from Solidesulfovibrio fructosivorans (formely Desulfovibrio fructosovorans) catalyses H2 oxidation and couples the exergonic reduction of NAD+ to the endergonic reduction of a ferredoxin by using a flavin-based electron-bifurcating mechanism.… read more here.
