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] $\rightleftharpoons$ plastoquinone + 2 reduced plastocyanin + 2 H⁺ [side 2]

Plastoquinol reductase contains two b-type cytochromes, two c-type cytochromes (cn and f), and a [2Fe-2S] Rieske cluster.
