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 -!- FUNCTION: NDH-1 shuttles electrons from NADH, via FMN and iron-sulfur
CC (Fe-S) centers, to quinones in the respiratory chain. The immediate
CC electron acceptor for the enzyme in this species is believed to be
CC ubiquinone. Couples the redox reaction to proton translocation (for
CC every two electrons transferred, four hydrogen ions are translocated
CC across the cytoplasmic membrane), and thus conserves the redox energy
CC in a proton gradient. {ECO:0000256|ARBA:ARBA00002378}.
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 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.
