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:0000305|PubMed:14610094}.
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 -!- SUBUNIT: NDH-1 is composed of at least 14 different subunits, Nqo1 to
CC Nqo14. The complex has a L-shaped structure, with the hydrophobic arm
CC (subunits Nqo7, Nqo8, Nqo10 to Nqo14) embedded in the inner membrane
CC and the hydrophilic peripheral arm (subunits Nqo1 to Nqo6, Nqo9)
CC protruding into the bacterial cytoplasm. The hydrophilic domain
CC contains all the redox centers (By similarity). NADH-quinone
CC oxidoreductase forms a supercomplex with ubiquinol-cytochrome c
CC reductase complex (complex III or cytochrome b-c1 complex) and
CC cytochrome c oxidase (complex IV), which stabilizes the NADH-quinone
CC oxidoreductase complex (PubMed:14610094). {ECO:0000250,
CC ECO:0000269|PubMed:14610094}.
CC -!- SUBCELLULAR LOCATION: Cell inner membrane
CC {ECO:0000305|PubMed:14610094}; Peripheral membrane protein
CC {ECO:0000305|PubMed:14610094}.
CC -!- SIMILARITY: Belongs to the complex I 49 kDa subunit family.
CC {ECO:0000305}.
