Accepted name: arsenate reductase (cytochrome c)
Reaction: arsenite + H2O + 2 oxidized cytochrome c = arsenate + 2 reduced cytochrome c + 2 H+
Other name(s): arsenite oxidase (ambiguous)
Systematic name: arsenite:cytochrome c oxidoreductase
Comments: A molybdoprotein containing iron-sulfur clusters. Isolated from α-proteobacteria. Unlike EC, arsenate reductase (azurin), it does not use azurin as acceptor.
