ID   2.5.1.32
DE   15-cis-phytoene synthase.
AN   geranylgeranyl-diphosphate geranylgeranyltransferase.
AN   phytoene synthetase.
AN   prephytoene-diphosphate synthase.
AN   PSase.
CA   2 (2E,6E,10E)-geranylgeranyl diphosphate = 15-cis-phytoene +
CA   2 diphosphate.
CC   -!- The enzyme condenses two molecules of geranylgeranyl diphosphate to
CC       give prephytoene diphosphate, followed by rearrangement of the
CC       cyclopropylcarbinyl intermediate to 15-cis-phytoene.
