- 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
editThis enzyme belongs to the family of oxidoreductases, specifically those acting on a heme group of donors with other acceptors.
Nomenclature
editThe systematic name of this enzyme class is ferrocytochrome-c:Fe3+ oxidoreductase. This enzyme is also called iron-cytochrome c reductase.
Structure and function
editThis enzyme is part of the electron transport system of Ferrobacillus ferrooxidans. It employs one cofactor, iron.
