Protein
NADH-quinone oxidoreductase subunit G
Gene
nuoG
Organism
Pseudomonas fluorescens
Status
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). Required for plants roots colonization.By similarity1 Publication
Catalytic activityi
