nuoE1

Gene
nuoE1
Protein
NADH-quinone oxidoreductase subunit E 1
Organism
Rhizobium meliloti (strain 1021)
Length
275 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 (By similarity).
Similarity
Belongs to the complex I 24 kDa subunit family.
Mass
29.906 kDa
