ENZYME entry: EC 4.2.3.33

Accepted Name
stemar-13-ene synthase.
Alternative Name(s)
stemarene synthase.
syn-stemar-13-ene synthase.
Reaction catalysed
9alpha-copalyl diphosphate <=> diphosphate + stemar-13-ene
Comment(s)
  • This diterpene cyclase produces stemar-13-ene, a putative precursor of the rice phytoalexin oryzalexin S.
  • 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.
