CC   -!- FUNCTION: NDH-1 shuttles electrons from NADH, via FMN and iron-
CC       sulfur (Fe-S) centers, to quinones in the respiratory chain. The
CC       immediate electron acceptor for the enzyme in this species is
CC       believed to be ubiquinone. Couples the redox reaction to proton
CC       translocation (for every two electrons transferred, four hydrogen
CC       ions are translocated across the cytoplasmic membrane), and thus
CC       conserves the redox energy in a proton gradient.
CC       {ECO:0000255|HAMAP-Rule:MF_01351}.
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,

CC   -!- COFACTOR:
CC       Name=[4Fe-4S] cluster; Xref=ChEBI:CHEBI:49883;
CC         Evidence={ECO:0000255|HAMAP-Rule:MF_01351};
CC       Note=Binds 2 [4Fe-4S] clusters per subunit. {ECO:0000255|HAMAP-
CC       Rule:MF_01351};
CC   -!- SUBUNIT: NDH-1 is composed of 14 different subunits. Subunits
CC       NuoA, H, J, K, L, M, N constitute the membrane sector of the
CC       complex. {ECO:0000255|HAMAP-Rule:MF_01351}.
CC   -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000255|HAMAP-
CC       Rule:MF_01351}; Peripheral membrane protein {ECO:0000255|HAMAP-
CC       Rule:MF_01351}.
CC   -!- SIMILARITY: Belongs to the complex I 23 kDa subunit family.
