KEGG   ENZYME: 1.20.2.1Help
Entry
EC 1.20.2.1                 Enzyme                                 

Name
arsenate reductase (cytochrome c);
arsenite oxidase (ambiguous)
Class
Oxidoreductases;
Acting on phosphorus or arsenic in donors;
With a cytochrome as acceptor
BRITE hierarchy
Sysname
arsenite:cytochrome c oxidoreductase
Reaction(IUBMB)
arsenite + H2O + 2 oxidized cytochrome c = arsenate + 2 reduced cytochrome c + 2 H+ [RN:R09787]
Reaction(KEGG)
Substrate
arsenite [CPD:C06697];
H2O [CPD:C00001];
oxidized cytochrome c
Product
arsenate [CPD:C11215];
reduced cytochrome c [CPD:C00126];
H+ [CPD:C00080]
Comment
A molybdoprotein containing iron-sulfur clusters. Isolated from alpha-proteobacteria. Unlike EC 1.20.9.1, arsenate reductase (azurin), it does not use azurin as acceptor.
History
EC 1.20.2.1 created 2011
