CC -!- FUNCTION: This enzyme recycles the H(2) produced by nitrogenase to
CC increase the production of ATP and to protect nitrogenase against
CC inhibition or damage by O(2) under carbon- or phosphate-limited
CC conditions. {ECO:0000256|ARBA:ARBA00037655}.
CC -!- COFACTOR:
CC Name=Fe cation; Xref=ChEBI:CHEBI:24875;
CC Evidence={ECO:0000256|PIRSR:PIRSR601501-1};
CC -!- COFACTOR:
CC Name=Ni(2+); Xref=ChEBI:CHEBI:49786;
CC Evidence={ECO:0000256|ARBA:ARBA00001967,
CC ECO:0000256|PIRSR:PIRSR601501-1};
CC -!- SUBUNIT: Heterodimer of a large and a small subunit.
CC {ECO:0000256|ARBA:ARBA00011771}.
CC -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000256|ARBA:ARBA00004202};
CC Peripheral membrane protein {ECO:0000256|ARBA:ARBA00004202}.
CC -!- SIMILARITY: Belongs to the [NiFe]/[NiFeSe] hydrogenase large subunit
CC family. {ECO:0000256|ARBA:ARBA00009292, ECO:0000256|RuleBase:RU003896}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
