General Information

EC Number General Information Comment Organism
1.20.2.1 physiological function the As(III) oxidation process in Ochrobacterium tritici requires not only the enzyme arsenite oxidase but also the cytochrome c encoded in the operon Brucella tritici
1.20.2.1 physiological function the As(III) oxidation process in Ochrobacterium tritici requires not only the enzyme arsenite oxidase but also the cytochrome c encoded in the operon. An aoxB deletion mutant fails to oxidize As(III) to As(V), but is able to grow in the presence of high arsenite concentrations Brucella tritici
