General annotation (Comments)

Function	NDH shuttles electrons from NAD(P)H:plastoquinone, via FMN and iron-sulfur (Fe-S) centers, to quinones in the photosynthetic chain and possibly in a chloroplast respiratory chain. The immediate electron acceptor for the enzyme in this species is believed to be plastoquinone. Couples the redox reaction to proton translocation, and thus conserves the redox energy in a proton gradient By similarity.
Catalytic activity	NAD(P)H + plastoquinone = NAD(P)+ + plastoquinol. HAMAP MF_01357
Subunit structure	NDH is composed of at least 16 different subunits, 5 of which are encoded in the nucleus By similarity.
Subcellular location	Plastid › chloroplast thylakoid membrane; Peripheral membrane protein; Stromal side By similarity.
Sequence similarities	Belongs to the complex I 30 kDa subunit family.
RNA editing	Edited at positions 20, 59, 64, 72, 82 and 110. Ref.1 Ref.2
