Term Name:	plastoquinol--plastocyanin reductase activity
Synonyms:	cytochrome b6f, cytochrome b6f complex activity, plastoquinol-plastocyanin reductase activity, plastoquinol/plastocyanin oxidoreductase activity, plastoquinol:oxidized-plastocyanin oxidoreductase activity
Definition:	Catalysis of the reaction: 2 H+[side 1] + 2 oxidized plastocyanin + plastoquinol-1 = 2 H+[side 2] + 2 reduced plastocyanin + plastoquinone. This reaction involves the concomitant transfer of 2 H+ ions across a membrane.
