ENZYME entry: EC 1.1.1.295

Accepted Name
Momilactone-A synthase.
Alternative Name(s)
Momilactone A synthase.
Reaction catalysed
3-beta-hydroxy-9-beta-pimara-7,15-diene-19,6-beta-olide + NAD(P)(+) <=> momilactone A + NAD(P)H
Comment(s)
  • The rice phytoalexin momilactone A is a diterpenoid secondary metabolite that is involved in the defense mechanism of the plant.
  • Momilactone A is produced in response to attack by a pathogen through the perception of elicitor signal molecules such as chitin oligosaccharide, or after exposure to UV irradiation.
  • The enzyme, which catalyzes the last step in the biosynthesis of momilactone A, can use both NAD(+) and NADP(+) but activity is higher with NAD(+).
