CC   -!- FUNCTION: NDH-1 shuttles electrons from an unknown electron donor, via
CC       FMN and iron-sulfur (Fe-S) centers, to quinones in the respiratory
CC       and/or the photosynthetic chain. The immediate electron acceptor for
CC       the enzyme in this species is believed to be plastoquinone. Couples the
CC       redox reaction to proton translocation, and thus conserves the redox
CC       energy in a proton gradient. Cyanobacterial NDH-1 also plays a role in
CC       inorganic carbon-concentration. {ECO:0000255|HAMAP-Rule:MF_01357}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=a plastoquinone + (n+1) H(+)(in) + NADH = a plastoquinol + n

CC   -!- SUBUNIT: NDH-1 can be composed of about 15 different subunits;
CC       different subcomplexes with different compositions have been identified
CC       which probably have different functions. {ECO:0000255|HAMAP-
CC       Rule:MF_01357}.
CC   -!- SUBCELLULAR LOCATION: Cellular thylakoid membrane {ECO:0000255|HAMAP-
CC       Rule:MF_01357}; Peripheral membrane protein {ECO:0000255|HAMAP-
CC       Rule:MF_01357}; Cytoplasmic side {ECO:0000255|HAMAP-Rule:MF_01357}.
CC   -!- SIMILARITY: Belongs to the complex I 30 kDa subunit family.
CC       {ECO:0000255|HAMAP-Rule:MF_01357}.
