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 + H(+) + NADH = a quinol + NAD(+);
CC Xref=Rhea:RHEA:46160, ChEBI:CHEBI:15378, ChEBI:CHEBI:24646,
CC ChEBI:CHEBI:57540, ChEBI:CHEBI:57945, ChEBI:CHEBI:132124;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_01357};
CC -!- SUBUNIT: NDH is composed of at least 16 different subunits, 5 of which
CC are encoded in the nucleus. {ECO:0000255|HAMAP-Rule:MF_01357}.
CC -!- SUBCELLULAR LOCATION: Plastid, organellar chromatophore thylakoid
CC membrane {ECO:0000250}; Peripheral membrane protein {ECO:0000255|HAMAP-
CC Rule:MF_01357}; Stromal side {ECO:0000255|HAMAP-Rule:MF_01357}.
CC -!- SIMILARITY: Belongs to the complex I 30 kDa subunit family.
CC {ECO:0000255|HAMAP-Rule:MF_01357}.
