Template:Short description Template:Infobox enzyme All-trans-phytoene synthase (Template:EC number, prephytoene-diphosphate synthase, phytoene synthetase, PSase, geranylgeranyl-diphosphate geranylgeranyltransferase, 15-trans-phytoene synthase) is an enzyme with systematic name geranylgeranyl-diphosphate:geranylgeranyl-diphosphate geranylgeranyltransferase (all-trans-phytoene forming).[1][2] This enzyme catalyses the following chemical reaction
- 2 geranylgeranyl diphosphate all-trans-phytoene + 2 diphosphate (overall reaction)
- (1a) 2 geranylgeranyl diphosphate diphosphate + prephytoene diphosphate
- (1b) prephytoene diphosphate all-trans-phytoene + diphosphate
This enzyme requires Mn2+ for activity.
