Comments

FUNCTION: This enzyme recycles the H(2) produced by nitrogenase to increase the production of ATP and to protect nitrogenase against inhibition or damage by O(2) under carbon- or phosphate-limited conditions.
CATALYTIC ACTIVITY: H₂ + A = AH₂.
COFACTOR: Binds 1 nickel ion per subunit (By similarity).
SUBUNIT: Heterodimer of a large and a small subunit.
SUBCELLULAR LOCATION: Cell membrane; Peripheral membrane protein.
PTM: 15 or 16 residues are removed from the C-terminus during maturation of the protein.
SIMILARITY: Belongs to the [NiFe]/[NiFeSe] hydrogenase large subunit family.
