Biol. Rep. 18:243-253(2000). CC -!- FUNCTION: NDH shuttles electrons from NAD(P)H:plastoquinone, via FMN CC and iron-sulfur (Fe-S) centers, to quinones in the photosynthetic chain CC and possibly in a chloroplast respiratory chain. The immediate electron CC acceptor for the enzyme in this species is believed to be CC plastoquinone. Couples the redox reaction to proton translocation, and CC thus conserves the redox energy in a proton gradient. CC {ECO:0000255|HAMAP-Rule:MF_01350}.
