IntEnz Enzyme Nomenclature
EC 1.20.2.1

Names

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

Reaction

Cofactors

Comments:

A molybdoprotein containing iron-sulfur clusters. Isolated from α-proteobacteria. Unlike EC 1.20.9.1, arsenate reductase (azurin), it does not use azurin as acceptor.
