Protein attributes

Sequence length	806 AA.
Sequence status	Complete.
Protein existence	Inferred from homology

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 menaquinone. 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.
Sequence similarities	Belongs to the complex I 75 kDa subunit family. Contains 1 2Fe-2S ferredoxin-type domain.
Sequence caution	The sequence AAK47578.1 differs from that shown. Reason: Erroneous initiation.
