shyB

Gene
shyB
Protein
Sulfhydrogenase 2 subunit beta
Organism
Pyrococcus furiosus (strain ATCC 43587 / DSM 3638 / JCM 8422 / Vc1)
Length
334 amino acids
Function
Part of a bifunctional enzyme complex that functions as a hydrogen-evolving hydrogenase with sulfur-reducing activity. May play a role in hydrogen cycling during fermentative growth. Activity exhibited with NAD in addition to NADPH. The beta and gamma subunits form the sulfur-reducing component that catalyzes the cytoplasmic production of hydrogen sulfide in the presence of elemental sulfur.
