Electrochemically driven catalysis of Rhizobium sp. NT-26 arsenite oxidase with its native electron acceptor cytochrome c552

We have achieved electrochemically driven catalytic arsenite oxidation using the periplasmic arsenite oxidase (Aio) from Rhizobium sp. str. NT-26 in concert with its natural electron transfer partner, cytochrome c552 (cyt c552), as a mediator and modeled the experimental voltammetry with electrochemical simulation to obtain a consistent set of rate constants for the ternary Aio/arsenite/cyt c552 system.75
