Protein attributes

Sequence length	417 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is not processed.
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. 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 FMN Potential. Binds 1 4Fe-4S cluster Potential.
Sequence similarities	Belongs to the complex I 51 kDa subunit family.
