In apoptosis, this protein combines with Apaf-1 to form the apoptosome heptamer.
This molecule accepts electrons from an enzyme that contains an iron-sulfur subunit known as a Rieske protein. This molecule acts as an electron donor to the P960 chlorophyll pair in some forms of bacterial photosynthesis, and interactions with it and its peroxidase play a prominent role in peroxide scavenging. A protein with a similar role to this one is the Diablo homolog, also known as SMAC. This molecule is released when proteins such as BID and Bax open up an oligomeric pore in the membrane of a certain organelle. (*) Cyanide poisoning functions by preventing this molecule's oxidase from reducing oxygen to water. In apoptosis, this protein combines with Apaf-1 to form the apoptosome heptamer. For ten points, name this iron-containing protein that passes electrons between complex III and complex IV in the electron transport chain.
