General annotation (Comments)

Function	NDH-1 shuttles electrons from NADH, via FMN and iron-sulfur (Fe-S) centers, to quinones in the respiratory chain. 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.
Cofactor	Binds 1 2Fe-2S cluster per subunit By similarity. Binds 3 4Fe-4S clusters per subunit By similarity.
Subunit structure	Composed of 13 different subunits. Subunits nuoCD, E, F, and G constitute the peripheral sector of the complex By similarity.
Sequence similarities	Belongs to the complex I 75 kDa subunit family. Contains 1 2Fe-2S ferredoxin-type domain.
