It functions as part of the electron transport chain and is the main subunit of transmembrane cytochrome bc1 and b6f complexes. Note that in some cases the trees are too large (have The path that leads to cytochrome c passes through an iron-sulfur cluster and then to a heme, which then passes the electron to cytochrome c. The first structures showed that the protein chain that holds the iron sulfur cluster flips back and forth, first bumping up against the ubiquinol and picking up the electron, then moving down to pass the electron to the heme. journal article that accompanies the website. help pages. representative proteomes (RP) sets, the UniProtKB sequence database, Cytochrome b6f uses a similar mechanism for linking electron transport to proton transport. The coenzyme Q : cytochrome c – oxidoreductase, sometimes called the cytochrome bc1 complex, and at other times complex III, is the third complex in the electron transport chain (EC 1.10.2.2), playing a critical role in biochemical generation of ATP (oxidative phosphorylation).
