ENZYME entry: EC 5.5.1.14

PURL: https://purl.expasy.org/enzyme/EC/5.5.1.14
Accepted Name
syn-copalyl-diphosphate synthase
Alternative Name(s)
syn-copalyl diphosphate synthase
syn-CPP synthase
Reaction catalysed
(2E,6E,10E)-geranylgeranyl diphosphate = 9alpha-copalyl diphosphate
Comment(s)
  • This class II terpene synthase produces syn-copalyl diphosphate, a precursor of several rice phytoalexins, including oryzalexin S and momilactones A and B.
  • Phytoalexins are diterpenoid secondary metabolites that are involved in the defense mechanism of the plant, and are produced in response to pathogen attack through the perception of elicitor signal molecules such as chitin oligosaccharide, or after exposure to UV irradiation.
  • Constitutively expressed in the roots of plants where one of its products, momilactone B, acts as an allelochemical (a molecule released into the environment to suppress the growth of neighboring plants).
  • In other tissues the enzyme is up-regulated by conditions that stimulate the biosynthesis of phytoalexins.
