Protein

Hydrogenase-1 large chain

Gene

hyaB

Organism
Escherichia coli (strain K12)
Status
Reviewed - Annotation score: 4 out of 5- Experimental evidence at protein leveli

Functioni

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 activityi

H2 + A = AH2.

Cofactori

Ni2+By similarityNote: Binds 1 nickel ion per subunit.By similarity
