 EC-number:  1.10.99.1 ----- plastoquinol-plastocyanin reductase
EC-NUMBER 1.10.99.1
ENZYME-NAME plastoquinol-plastocyanin reductase
ENZYME-SYSNAME A cytochrome f,b6 complex separated from chloroplasts. Also acts, more slowly, on plastoquinol-9 and ubiquinols. Cytochrome c-552 can act instead of plastocyanin, but more slowly.
ENZYME-CLASS Oxidoreductases Acting on diphenols and related substances as donors With other acceptors
SYNONYMS cytochrome b6/ complex; cytochrome b6/f complex;; plastoquinol-plastocyanin reductase;; plastoquinol/plastocyanin oxidoreductase;;   >>more synonyms
REACTION plastoquinol-1 + 2 oxidized plastocyanin = plastoquinone + 2 reduced plastocyanin [RN:R03817]
PATHWAY EMP-PATHWAYS: NO EMP PATHWAY FOUND
KEGG-PATHWAYS: Photosynthesis;   >>more KEGG pathways
GO_TERM GO:0009496:plastoquinol-plastocyanin reductase activity
