OC Eukaryota; Metazoa; Chordata; Craniata; Vertebrata; Cyclostomata; OC Hyperoartia; Petromyzontiformes; Petromyzontidae; Entosphenus. OX NCBI_TaxID=245074; RN [1] RP PROTEIN SEQUENCE OF 2-105, AND ACETYLATION AT GLY-2. RX PubMed=4355549; DOI=10.1021/bi00745a005; RA Nolan C., Fitch W.M., Uzzell T., Weiss L.J., Margoliash E.; RT "Amino acid sequence of a cytochrome c from the common Pacific lamprey, RT Entosphenus tridentatus."; RL Biochemistry 12:4052-4060(1973). 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}.
