ENZYME entry: EC 2.5.1.32

Accepted Name
Phytoene synthase.
Alternative Name(s)
Geranylgeranyl-diphosphate geranylgeranyltransferase.
Phytoene synthetase.
Prephytoene-diphosphate synthase.
PSase.
Reaction catalysed
  • 2 geranylgeranyl diphosphate <=> diphosphate + prephytoene diphosphate
  • Prephytoene diphosphate <=> phytoene + diphosphate
Cofactor(s)
Manganese.
Comment(s)
  • The enzyme appears to be stereospecific, normally producing 15-cis- phytoene.
  • However, in Erwinia herbicola, the product is the 15-trans isomer.
