Enzyme Commission Number
EC 7.1.1.6
Product Overview
High-quality enzyme products.
Well-established quality management system.
Reaction
plastoquinol + 2 oxidized plastocyanin + 2 H+[side 1] = plastoquinone + 2 reduced plastocyanin + 4 H+[side 2]
Systematic Name
plastoquinol:oxidized-plastocyanin oxidoreductase
Function
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 stroma to the lumen. The mechanism occurs through the Q cycle as in EC 7.1.1.8, quinol—cytochrome-c reductase (complex III) and involves electron bifurcation.
