CC   -!- FUNCTION: NDH shuttles electrons from NAD(P)H:plastoquinone, via
CC       FMN and iron-sulfur (Fe-S) centers, to quinones in the
CC       photosynthetic chain and possibly in a chloroplast respiratory
CC       chain. The immediate electron acceptor for the enzyme in this
CC       species is believed to be plastoquinone. Couples the redox
CC       reaction to proton translocation, and thus conserves the redox
CC       energy in a proton gradient. {ECO:0000255|HAMAP-Rule:MF_01351}.
