ENZYME entry: EC 5.4.99.39

Accepted Name
Beta-amyrin synthase.
Alternative Name(s)
2,3-oxidosqualene beta-amyrin cyclase.
Reaction catalysed
(3S)-2,3-epoxy-2,3-dihydrosqualene <=> beta-amyrin
Comment(s)
  • Some organism possess a monofunctional beta-amyrin synthase, other have a multifunctional enzyme that also catalyzes the synthesis of alpha-amyrin (EC 5.4.99.40) or lupeol (EC 5.4.99.41).
