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_01456}.
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_01456};
CC   -!- SUBUNIT: NDH is composed of at least 16 different subunits, 5 of which
CC       are encoded in the nucleus. {ECO:0000255|HAMAP-Rule:MF_01456}.
CC   -!- SUBCELLULAR LOCATION: Plastid, chloroplast thylakoid membrane
CC       {ECO:0000255|HAMAP-Rule:MF_01456}; Multi-pass membrane protein
CC       {ECO:0000255|HAMAP-Rule:MF_01456}.
CC   -!- SIMILARITY: Belongs to the complex I subunit 4L family.
