OX NCBI_TaxID=5271; RN [1] RP PROTEIN SEQUENCE. RC STRAIN=ATCC 12421 / CBS 534.71 / IMI 61828 / 50-135; RX PubMed=4349112; DOI=10.1042/bj1290561; RA Bitar K.G., Vinogradov S.N., Nolan C., Weiss L.J., Margoliash E.; RT "The primary structure of cytochrome c from the rust fungus Ustilago RT sphaerogena."; RL Biochem. J. 129:561-569(1972). CC -!- FUNCTION: Electron carrier protein. The oxidized form of the cytochrome CC c heme group can accept an electron from the heme group of the CC cytochrome c1 subunit of cytochrome reductase. Cytochrome c then CC transfers this electron to the cytochrome oxidase complex, the final CC protein carrier in the mitochondrial electron-transport chain. CC -!- SUBCELLULAR LOCATION: Mitochondrion intermembrane space. Note=Loosely CC associated with the inner membrane. CC -!- PTM: Binds 1 heme c group covalently per subunit. CC -!- SIMILARITY: Belongs to the cytochrome c family. {ECO:0000305}.
