nuoC2

Gene
nuoC2
Protein
NADH-quinone oxidoreductase subunit C/D 2
Organism
Aquifex aeolicus (strain VF5)
Length
586 amino acids
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.
Similarity
In the C-terminal section; belongs to the complex I 49 kDa subunit family.
Mass
67.893 kDa
