hydB Protein, Pyrococcus furiosus (His)

HydB is an important component of the bifunctional enzyme complex and is a NADPH-dependent hydrogen-evolving hydrogenase with sulfur reducing activity. It contributes to the hydrogen cycle during fermentative growth, with the beta and gamma subunits catalyzing the cytoplasmic production of hydrogen sulfide from elemental sulfur. hydB Protein, Pyrococcus furiosus (His) is the recombinant hydB protein, expressed by E. coli , with N-6*His labeled tag.

HydB is a component of a bifunctional enzyme complex, acting as an NADPH-dependent hydrogen-evolving hydrogenase with sulfur reducing activity. This enzyme may contribute to hydrogen cycling during fermentative growth. Notably, its activity is not demonstrated with NAD, and the beta and gamma subunits together form the sulfur-reducing component responsible for catalyzing the cytoplasmic production of hydrogen sulfide in the presence of elemental sulfur. However, HydB is inactive when exposed to sodium sulfate, sodium sulfite, sodium thiosulfate, or cysteine. These findings highlight its role in the intricate processes of hydrogen metabolism and sulfur reduction, specifically under certain environmental conditions.
