WebCytochrome c, shown here from PDB entry 3cyt , is a carrier of electrons. Like many proteins that carry electrons, it contains a special prosthetic group that handles the slippery electrons. Cytochrome c contains a heme group with an iron ion gripped tightly inside, colored red here. The iron ion readily accepts and releases an electron. WebFeb 21, 1997 · Cytochrome c release was unaccompanied by changes in mitochondrial membrane potential. Thus, Bcl-2 acts to inhibit cytochrome c translocation, thereby blocking caspase activation and the apoptotic process. Bcl-2 and its relatives (for example, Bcl-x, E1B 19K, and CED-9) are potent inhibitors of apoptotic cell death ( 1 – 3 ). javascript print image base64WebThe enzyme cytochrome c oxidase or Complex IV, (was EC 1.9.3.1, now reclassified as a translocase EC 7.1.1.9) is a large transmembrane protein complex found in bacteria, archaea, and mitochondria of eukaryotes.
