CC   -!- FUNCTION: This is one of three E.coli hydrogenases synthesized in
CC       response to different physiological conditions. HYD2 is involved
CC       in hydrogen uptake (By similarity).
CC   -!- CATALYTIC ACTIVITY: H(2) + A = AH(2).
CC   -!- COFACTOR: Binds 1 nickel ion per subunit (By similarity).
CC   -!- SUBUNIT: Heterodimer of a large and a small subunit (By
CC       similarity).
CC   -!- SUBCELLULAR LOCATION: Cell membrane; Peripheral membrane protein
CC       (By similarity).
CC   -!- SIMILARITY: Belongs to the [NiFe]/[NiFeSe] hydrogenase large
CC       subunit family.
