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. {ECO:0000305}.
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   -!- CATALYTIC ACTIVITY:
CC       Reaction=a plastoquinone + (n+1) H(+)(in) + NADPH = a plastoquinol + n
CC         H(+)(out) + NADP(+); Xref=Rhea:RHEA:42612, Rhea:RHEA-COMP:9561,

CC         Evidence={ECO:0000305};
CC   -!- SUBUNIT: Part of the chloroplast NDH complex, composed of a mixture of
CC       chloroplast and nucleus encoded subunits. Component of the NDH
CC       subcomplex A, at least composed of ndhH, ndhI, ndhJ, ndhK, ndhL, ndhM,
CC       ndhN and ndhO. {ECO:0000250|UniProtKB:Q2V2S7}.
CC   -!- SUBCELLULAR LOCATION: Plastid, chloroplast thylakoid membrane
CC       {ECO:0000250|UniProtKB:Q9CAC5}; Peripheral membrane protein
CC       {ECO:0000305}; Stromal side {ECO:0000305}.
CC   -!- SIMILARITY: Belongs to the NDH complex subunit M family. {ECO:0000305}.
