Comments

FUNCTION: Electron carrier protein. The oxidized form of the cytochrome c heme group can accept an electron from the heme group of the cytochrome c1 subunit of cytochrome reductase. Cytochrome c then transfers this electron to the cytochrome oxidase complex, the final protein carrier in the mitochondrial electron-transport chain.
SUBCELLULAR LOCATION: Mitochondrion matrix.
PTM: Binds 1 heme group per subunit.
MISCELLANEOUS: Mules and hinnies are heterozygous, having equal amount of horse and donkey cytochromes c.
SIMILARITY: Belongs to the cytochrome c family.
