Protein attributes

Sequence length	108 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is further processed into a mature form.
Protein existence	Evidence at protein level.

General annotation (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.
Post-translational modification	Binds 1 heme group per subunit.
Sequence similarities	Belongs to the cytochrome c family.
