1.20.2.1	cytochrome c-551	physiological electron acceptor for the arsenite oxidase	658195	
1.20.2.1	cytochrome c552	native electron transfer partner	727089	
1.20.2.1	cytochrome c552	physiological electron acceptor to the arsenite oxidase, the gene that encodes this protein is located downstream of the arsenite oxidase genes aroBA. Characterisation reveals the presence of a single heme per protein and that the heme redox potential is similar to that of mitochondrial c-type cytochromes	714304	
1.20.2.1	iron-sulfur centre	the large subunit aoxB has the [3Fe-4S] cluster-binding motif as well as the residues proposed to bind arsenite	714842	
1.20.2.1	iron-sulfur centre	the small subunit aoxA has a characteristic Tat signal sequence and contains the residues binding the [2Fe-2S] Rieske-type cluster	714842	
1.20.2.1	molybdenum cofactor	-	714842	
1.20.2.1	molybdenum cofactor	protein contains two molybdenum and 9 or 10 iron atoms per alpha2beta2 unit	715352
