CC   -!- FUNCTION: NDH-1 shuttles electrons from NADH, via FMN and iron-sulfur
CC       (Fe-S) centers, to quinones in the respiratory chain. Couples the redox
CC       reaction to proton translocation (for every two electrons transferred,
CC       four hydrogen ions are translocated across the cytoplasmic membrane),
CC       and thus conserves the redox energy in a proton gradient (By
CC       similarity). {ECO:0000250}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=a quinone + 5 H(+)(in) + NADH = a quinol + 4 H(+)(out) +
CC         NAD(+); Xref=Rhea:RHEA:57888, ChEBI:CHEBI:15378, ChEBI:CHEBI:24646,

CC   -!- COFACTOR:
CC       Name=[2Fe-2S] cluster; Xref=ChEBI:CHEBI:190135; Evidence={ECO:0000250};
CC       Note=Binds 1 [2Fe-2S] cluster per subunit. {ECO:0000250};
CC   -!- COFACTOR:
CC       Name=[4Fe-4S] cluster; Xref=ChEBI:CHEBI:49883; Evidence={ECO:0000250};
CC       Note=Binds 2 [4Fe-4S] clusters per subunit. {ECO:0000250};
CC   -!- SIMILARITY: Belongs to the complex I 75 kDa subunit family.
