CC -!- FUNCTION: NDH-1 shuttles electrons from NAD(P)H, 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 believed
CC to be plastoquinone. Couples the redox reaction to proton translocation
CC (for every two electrons transferred, four hydrogen ions are
CC translocated across the cytoplasmic membrane), and thus conserves the
CC redox energy in a proton gradient. {ECO:0000255|HAMAP-Rule:MF_00491}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=a plastoquinone + (n+1) H(+)(in) + NADH = a plastoquinol + n
CC H(+)(out) + NAD(+); Xref=Rhea:RHEA:42608, Rhea:RHEA-COMP:9561,
