EC Number: 1.20.2.1

Enzymes and Genes:

arsenite-oxidizing bacterium NT-14: arsenite oxidoreductaseInferred from experiment

In Pathway: arsenite oxidation I (respiratory)

Transport reaction diagram

Reaction Locations: inner membrane (sensu Gram-negative Bacteria)

The direction shown, i.e. which substrates are on the left and right sides, is in accordance with the Enzyme Commission system.

Most BioCyc compounds have been protonated to a reference pH value of 7.3. Please see the PGDB Concepts Guide for more information.

Mass balance status: Balanced.

Enzyme Commission Primary Name: arsenate reductase (cytochrome c)

Enzyme Commission Synonyms: arsenite oxidase (ambiguous)

Standard Gibbs Free Energy (ΔrG in kcal/mol): -0.25228882Inferred by computational analysis [Latendresse13]

Enzyme Commission Summary:
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.
