Plastoquinol/plastocyanin reductase
Plastoquinol/plastocyanin reductase (EC 1.10.9.1, plastoquinol/plastocyanin oxidoreductase, cytochrome f/b6 complex) is an enzyme with systematic name plastoquinol:oxidized-plastocyanin oxidoreductase.[1][2] This enzyme catalyses the following chemical reaction
- plastoquinol + 2 oxidized plastocyanin + 2 H+ [side 1] plastoquinone + 2 reduced plastocyanin + 2 H+ [side 2]
