nqo6

Gene
nqo6
Protein
NADH-quinone oxidoreductase subunit 6
Organism
Thermus thermophilus (strain HB8 / ATCC 27634 / DSM 579)
Length
181 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 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 required for the synthesis of ATP.
Similarity
Belongs to the complex I 20 kDa subunit family.
Mass
20.239 kDa

Length
173 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.
