NADH-quinone oxidoreductase subunit G

Gene

nuoG

Organism
Yersinia pestis
Status
Reviewed-Annotation score: -Protein inferred from homologyi

Functioni

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).By similarity

Catalytic activityi

NADH + a quinone = NAD+ + a quinol.

Cofactori

Protein has several cofactor binding sites:
  • [2Fe-2S] clusterBy similarityNote: Binds 1 [2Fe-2S] cluster per subunit.By similarity
  • [4Fe-4S] clusterBy similarityNote: Binds 3 [4Fe-4S] clusters per subunit.By similarity
