Protein

Ion-translocating oxidoreductase complex subunit B

Gene

rsxB

Organism
Escherichia coli (strain K12)
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

Part of a membrane-bound complex that couples electron transfer with translocation of ions across the membrane (By similarity). Required to maintain the reduced state of SoxR. Probably transfers electron from NAD(P)H to SoxR (PubMed:12773378).UniRule annotation1 Publication
