General annotation (Comments)

Function	NDH-1 shuttles electrons from NADH, via FMN and iron-sulfur (Fe-S) centers, to quinones in the respiratory chain. The immediate electron acceptor for the enzyme in this species is believed to be ubiquinone. Couples the redox reaction to proton translocation (for every two electrons transferred, four hydrogen ions are translocated across the cytoplasmic membrane), and thus conserves the redox energy in a proton gradient By similarity.
Catalytic activity	NADH + quinone = NAD+ + quinol. HAMAP MF_01357
Subunit structure	NDH-1 is composed of 14 different subunits. Subunits nuoB, C, D, E, F, and G constitute the peripheral sector of the complex By similarity.
Subcellular location	Cell inner membrane; Peripheral membrane protein; Cytoplasmic side By similarity.
Sequence similarities	Belongs to the complex I 30 kDa subunit family.
