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_01394}.
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,

CC Evidence={ECO:0000255|HAMAP-Rule:MF_01394};
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_01394}.
CC -!- SUBCELLULAR LOCATION: Cellular thylakoid membrane {ECO:0000255|HAMAP-
CC Rule:MF_01394}; Multi-pass membrane protein {ECO:0000255|HAMAP-
CC Rule:MF_01394}.
CC -!- SIMILARITY: Belongs to the complex I subunit 3 family.
CC {ECO:0000255|HAMAP-Rule:MF_01394}.
