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.
CC {ECO:0000256|RuleBase:RU003525}.
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 ChEBI:CHEBI:57540, ChEBI:CHEBI:57945, ChEBI:CHEBI:132124;
CC Evidence={ECO:0000256|ARBA:ARBA00000100,

CC -!- COFACTOR:
CC Name=[2Fe-2S] cluster; Xref=ChEBI:CHEBI:190135;
CC Evidence={ECO:0000256|RuleBase:RU003525};
CC Note=Binds 1 [2Fe-2S] cluster per subunit.
CC {ECO:0000256|RuleBase:RU003525};
CC -!- COFACTOR:
CC Name=[4Fe-4S] cluster; Xref=ChEBI:CHEBI:49883;
CC Evidence={ECO:0000256|ARBA:ARBA00001966,
CC ECO:0000256|RuleBase:RU003525};
CC -!- SUBUNIT: Composed of 13 different subunits. Subunits NuoCD, E, F, and G
CC constitute the peripheral sector of the complex.
CC {ECO:0000256|ARBA:ARBA00026021}.
CC -!- SIMILARITY: Belongs to the complex I 75 kDa subunit family.
CC {ECO:0000256|ARBA:ARBA00005404, ECO:0000256|RuleBase:RU003525}.
