| Comments |
Contains two?b-type cytochromes, two?c-type cytochromes (cn?and?f), and a [2Fe-2S] Rieske cluster. The enzyme plays a key role in photosynthesis, transferring electrons from photosystem II (EC?1.10.3.9) to photosystem I (EC?1.97.1.12). Cytochrome?c-552 can act as acceptor instead of plastocyanin, but more slowly. In chloroplasts, protons are translocated through the thylakoid membrane from the lumen to the stroma. The mechanism occurs through the Q cycle as in EC?7.1.1.8, quinol¡ªcytochrome-c reductase (complex III) and involves electron bifurcation. Formerly EC?1.10.99.1. |
