Cytochrome c 7

GeneralGeneral

Cytocrhome c 7 (Cc7) is a three heme-containing protein derived from the sulfur-reducing bacterium Desulfuromonas acetoxidans. Cc7 is located in the mitochondrial intermembrane space of the bacteria where it plays a role in the electron-transfer mechanism ^[1]. Desulfuromonas acetoxidans bacteria have evolved to obtain their energy from anaerobic sulfure respiration, thus requiring organic disulfide compounds as electron acceptors^[2].
