Protein
NADH-quinone oxidoreductase subunit B
Gene
nuoB, BU155
Organism
Buchnera aphidicola subsp. Acyrthosiphon pisum (strain APS) (Acyrthosiphon pisum symbiotic bacterium)
Status
Reviewed - Annotation score: 3 out of 5 - 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. 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.UniRule annotation

Catalytic activityi

NADH + quinone = NAD+ + quinol.UniRule annotation

Cofactori

Binds 1 4Fe-4S cluster By similarity.UniRule annotation
