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.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=A + H2 = AH2; Xref=Rhea:RHEA:12116, ChEBI:CHEBI:13193,
CC ChEBI:CHEBI:17499, ChEBI:CHEBI:18276; EC=1.12.99.6;
CC -!- COFACTOR:
CC Name=[3Fe-4S] cluster; Xref=ChEBI:CHEBI:21137; Evidence={ECO:0000250};
CC Note=Binds 1 [3Fe-4S] cluster. {ECO:0000250};
CC -!- COFACTOR:
CC Name=[4Fe-4S] cluster; Xref=ChEBI:CHEBI:49883; Evidence={ECO:0000250};
CC Note=Binds 2 [4Fe-4S] clusters. {ECO:0000250};
CC -!- SUBUNIT: Heterodimer of a large and a small subunit.
CC -!- SUBCELLULAR LOCATION: Cell membrane; Peripheral membrane protein.
CC -!- PTM: Predicted to be exported by the Tat system. The position of the
CC signal peptide cleavage has not been experimentally proven.
CC -!- SIMILARITY: Belongs to the [NiFe]/[NiFeSe] hydrogenase small subunit
CC family. {ECO:0000305}.
