Comments

FUNCTION: This is one of three E.coli hydrogenases synthesized in response to different physiological conditions. HYD1 is believed to have a role in hydrogen cycling during fermentative growth.
CATALYTIC ACTIVITY: H₂ + A = AH₂.
COFACTOR: Binds 1 nickel ion per subunit (By similarity).
SUBUNIT: Heterodimer of a large and a small subunit.
INTERACTION:
P28912:yhhI; NbExp=1; IntAct=EBI-851493, EBI-1115282;
SUBCELLULAR LOCATION: Cell membrane; Peripheral membrane protein.
SIMILARITY: Belongs to the [NiFe]/[NiFeSe] hydrogenase large subunit family.
