7.3.2.7 | additional information | The ArsA protein exhibits ATPase activity with a strict requirement for arsenite or antimonite. The binding of the ArsA protein to the ArsB protein on the inner membrane forms an active pump complex which catalyzes oxyanion transport, ArsB functions as the membrane anchor for the ArsA protein | Escherichia coli | ? | - |
