Appl. Microbiol. 33:122-127(2010). 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:0000256|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, ChEBI:CHEBI:24646, CC ChEBI:CHEBI:57540, ChEBI:CHEBI:57945, ChEBI:CHEBI:132124; CC Evidence={ECO:0000256|HAMAP-Rule:MF_01351}; CC -!- COFACTOR: CC Name=[4Fe-4S] cluster; Xref=ChEBI:CHEBI:49883; CC Evidence={ECO:0000256|HAMAP-Rule:MF_01351}; CC Note=Binds 2 [4Fe-4S] clusters per subunit. {ECO:0000256|HAMAP- CC Rule:MF_01351}; CC -!- SUBUNIT: NDH-1 is composed of 14 different subunits. Subunits NuoA, H, CC J, K, L, M, N constitute the membrane sector of the complex. CC {ECO:0000256|HAMAP-Rule:MF_01351}.
