UniProtKB - Q68VV2 (NUOG_RICTY)
Protein
NADH-quinone oxidoreductase subunit G
Gene
nuoG
Organism
Rickettsia typhi (strain ATCC VR-144 / Wilmington)
Status
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).By similarity
Catalytic activityi
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 2 [4Fe-4S] clusters per subunit.By similarity
