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. {ECO:0000255|HAMAP-Rule:MF_01350}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=a plastoquinone + (n+1) H(+)(in) + NADH = a plastoquinol + n

CC -!- SUBUNIT: NDH-1 is composed of at least 11 different subunits.
CC {ECO:0000255|HAMAP-Rule:MF_01350}.
CC -!- SUBCELLULAR LOCATION: Cellular thylakoid membrane {ECO:0000255|HAMAP-
