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 ECO:0000256|RuleBase:RU003525};
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 -!- SIMILARITY: Belongs to the complex I 75 kDa subunit family.
CC {ECO:0000256|ARBA:ARBA00005404, ECO:0000256|RuleBase:RU003525}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
