ID 1.16.2.1 DE iron--cytochrome-c reductase. AN iron-cytochrome c reductase. CA Fe(3+) + Fe(II)-[cytochrome c] = Fe(2+) + Fe(III)-[cytochrome c]. CC -!- The MtrC and OmcA proteins of the bacterium Shewanella oneidensis CC MR-1 are decaheme c-type cytochromes that reduce iron oxides CC extracellularly, passing the electrons to MtrA, another decaheme CC c-type cytochrome located in the periplasm. CC -!- Formerly EC 1.9.98.1. //
