}}All-trans-phytoene synthase ({{EC number|2.5.1.99}}, 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.
