Accepted name: | 15-cis-phytoene synthase | ||||||||||
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 |

Other name(s): | PSY (gene name); crtB (gene name); prephytoene-diphosphate synthase; phytoene synthetase; PSase; geranylgeranyl-diphosphate geranylgeranyltransferase | ||||||||||
Systematic name: | geranylgeranyl-diphosphate:geranylgeranyl-diphosphate geranylgeranyltransferase (15-cis-phytoene-forming) | ||||||||||
Comments: | Requires Mn2+ for activity. The enzyme condenses two molecules of geranylgeranyl diphosphate to give prephytoene diphosphate, followed by rearrangement of the cyclopropylcarbinyl intermediate to 15-cis-phytoene. | ||||||||||
