Cofactor

Cofactor Comment Organism Structure
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 arsenite-oxidising bacterium
