IntEnz Enzyme Nomenclature


Accepted name:
arsenate reductase (cytochrome c)
Other name:
arsenite oxidase
Systematic name:
arsenite:cytochrome c oxidoreductase




A molybdoprotein containing iron-sulfur clusters. Isolated from α-proteobacteria. Unlike EC, arsenate reductase (azurin), it does not use azurin as acceptor.
