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 ChEBI:CHEBI:57540, ChEBI:CHEBI:57945, ChEBI:CHEBI:132124;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_01356};
CC -!- COFACTOR:
CC Name=[4Fe-4S] cluster; Xref=ChEBI:CHEBI:49883;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_01356};
CC Note=Binds 1 [4Fe-4S] cluster. {ECO:0000255|HAMAP-Rule:MF_01356};
CC -!- SUBUNIT: NDH-1 is composed of 14 different subunits. Subunits NuoB, C,
CC D, E, F, and G constitute the peripheral sector of the complex.
CC {ECO:0000255|HAMAP-Rule:MF_01356}.
CC -!- SUBCELLULAR LOCATION: Cell inner membrane {ECO:0000255|HAMAP-
CC Rule:MF_01356}; Peripheral membrane protein {ECO:0000255|HAMAP-
CC Rule:MF_01356}; Cytoplasmic side {ECO:0000255|HAMAP-Rule:MF_01356}.
CC -!- SIMILARITY: Belongs to the complex I 20 kDa subunit family.
CC {ECO:0000255|HAMAP-Rule:MF_01356}.
CC -!- SEQUENCE CAUTION:
CC Sequence=CAP42017.1; Type=Erroneous initiation; Evidence={ECO:0000305};
