In enzymology, an iron—cytochrome-c reductase (created 1972 as EC 1.9.99.1, transferred 2014 to EC 1.9.98.1) is an enzyme that catalyzes the chemical reaction

ferrocytochrome c + Fe3+ ferricytochrome c + Fe2+

Thus, the two substrates of this enzyme are ferrocytochrome c and Fe3+, whereas its two products are ferricytochrome c and Fe2+.

Classification

[edit]

This enzyme belongs to the family of oxidoreductases, specifically those acting on a heme group of donors with other acceptors.

Nomenclature

[edit]

The systematic name of this enzyme class is ferrocytochrome-c:Fe3+ oxidoreductase. This enzyme is also called iron-cytochrome c reductase.

Structure and function

[edit]

This enzyme is part of the electron transport system of Ferrobacillus ferrooxidans. It employs one cofactor, iron.
