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       Cyanobacterial NDH-1 also plays a role in inorganic carbon-
CC       concentration. {ECO:0000255|HAMAP-Rule:MF_01354}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=a plastoquinone + (n+1) H(+)(in) + NADH = a plastoquinol
CC         + n H(+)(out) + NAD(+); Xref=Rhea:RHEA:42608, Rhea:RHEA-

CC   -!- SUBUNIT: NDH-1 can be composed of about 15 different subunits;
CC       different subcomplexes with different compositions have been
CC       identified which probably have different functions.
CC       {ECO:0000255|HAMAP-Rule:MF_01354}.
CC   -!- SUBCELLULAR LOCATION: Cellular thylakoid membrane
CC       {ECO:0000255|HAMAP-Rule:MF_01354}; Peripheral membrane protein
CC       {ECO:0000255|HAMAP-Rule:MF_01354}; Cytoplasmic side
CC       {ECO:0000255|HAMAP-Rule:MF_01354}.
CC   -!- SIMILARITY: Belongs to the complex I NdhO subunit family.
