Taxonomic identifier

272947 [NCBI]

Taxonomic lineage

Bacteria › Proteobacteria › Alphaproteobacteria › Rickettsiales › Rickettsiaceae › Rickettsieae › Rickettsia › typhus group

Protein attributes

Sequence length	421 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. 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.
