La phytoène synthase est une enzyme de type transférase impliquée dans la biosynthèse de caroténoïdes. Elle catalyse la conversion du pyrophosphate de géranylgéranyle en phytoène. (fr) Phytoene synthase (EC 2.5.1.32, prephytoene-diphosphate synthase, 15-cis-phytoene synthase, PSase, geranylgeranyl-diphosphate geranylgeranyltransferase) is a transferase enzyme involved in the biosynthesis of carotenoids. It catalyzes the conversion of geranylgeranyl pyrophosphate to phytoene. This enzyme catalyses the following chemical reaction 2 geranylgeranyl diphosphate 15-cis-phytoene + 2 diphosphate (overall reaction)(1a) 2 geranylgeranyl diphosphate diphosphate + prephytoene diphosphate(1b) prephytoene diphosphate 15-cis-phytoene + diphosphate This enzyme requires Mn2+ for activity. It belongs to squalene/phytoene synthase family of proteins. (en) |
