Protein

Periplasmic [NiFe] hydrogenase large subunit

Gene

hydB

Organism
Desulfovibrio vulgaris (strain Miyazaki F / DSM 19637)
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

Catalyzes the reversible oxidoreduction of molecular hydrogen, in conjunction with a specific electron acceptor, cytochrome c3.

Miscellaneous

Perhaps the leader of the small subunit serves as a transport vehicle for both subunits.

Catalytic activityi

H2 + 2 ferricytochrome c3 = 2 H+ + 2 ferrocytochrome c3.

Cofactori

Protein has several cofactor binding sites:
