General annotation (Comments)

Function	NDH-1 shuttles electrons from an unknown electron donor, via FMN and iron-sulfur (Fe-S) centers, to quinones in the respiratory and/or the photosynthetic 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_01350
Subunit structure	NDH-1 is composed of at least 11 different subunits By similarity.
Subcellular location	Cellular thylakoid membrane; Multi-pass membrane protein By similarity.
Sequence similarities	Belongs to the complex I subunit 1 family.
