CC   -!- FUNCTION: NDH-1 shuttles electrons from an unknown electron donor,
CC       via FMN and iron-sulfur (Fe-S) centers, to quinones in the
CC       respiratory and/or the photosynthetic chain. The immediate
CC       electron acceptor for the enzyme in this species is believed to be
CC       plastoquinone. Couples the redox reaction to proton translocation,
CC       and thus conserves the redox energy in a proton gradient.
CC       {ECO:0000255|HAMAP-Rule:MF_01351}.

CC       Rule:MF_01351};
CC   -!- SUBUNIT: NDH-1 is composed of at least 11 different subunits.
CC       {ECO:0000255|HAMAP-Rule:MF_01351}.
