Comments

FUNCTION: Subunits alpha and gamma of hoxS constitute an NADH--oxidoreductase.
CATALYTIC ACTIVITY: H₂ + NAD⁺ = H⁺ + NADH.
COFACTOR: Binds 3 4Fe-4S clusters per subunit (Potential).
SUBUNIT: Tetramer of an alpha and a gamma subunits (flavin-containing dimer), and a delta and a nickel-containing beta subunits (hydrogenase dimer).
SUBCELLULAR LOCATION: Cytoplasm.
SIMILARITY: Belongs to the complex I 75 kDa subunit family.
SIMILARITY: Contains 1 2Fe-2S ferredoxin-type domain.
