An essential role of the reversible electron-bifurcating hydrogenase Hnd for ethanol oxidation in Solidesulfovibrio fructosivorans Open
The tetrameric cytoplasmic FeFe hydrogenase Hnd from Solidesulfovibrio fructosivorans (formely Desulfovibrio fructosovorans ) catalyses H 2 oxidation and couples the exergonic reduction of NAD + to the endergonic reduction of a ferredoxin …

Carbon Fixation in the Chemolithoautotrophic Bacterium Aquifex aeolicus Involves Two Low-Potential Ferredoxins as Partners of the PFOR and OGOR Enzymes Open
Aquifex aeolicus is a microaerophilic hydrogen- and sulfur -oxidizing bacterium that assimilates CO2 via the reverse tricarboxylic acid cycle (rTCA). Key enzymes of this pathway are pyruvate:ferredoxin oxidoreductase (PFOR) and 2-oxoglutar…
