KEGG ENZYME: 1.16.9.1

ENZYME: 1.16.9.1

Entry

EC 1.16.9.1                 Enzyme

Name

iron:rusticyanin reductase;
Cyc2 (ambiguous)

Class

Oxidoreductases;
Oxidizing metal ions;
With a copper protein as acceptor

Sysname

Fe(II):rusticyanin oxidoreductase

Reaction(IUBMB)

Fe(II) + rusticyanin = Fe(III) + reduced rusticyanin

Substrate

Fe(II) [CPD:C14818];
rusticyanin

Product

Fe(III) [CPD:C14819];
reduced rusticyanin

Comment

Contains c-type heme. The enzyme in Acidithiobacillus ferrooxidans is a component of an electron transfer chain from Fe(II), comprising this enzyme, the copper protein rusticyanin, cytochrome c4, and cytochrome c oxidase (EC 7.1.1.9).

History
