EC 4.2.3.229     
Accepted name: ent-beyerene synthase
Reaction: ent-copalyl diphosphate = ent-beyerene + diphosphate

Glossary: ent-beyerene = ent-beyer-15-ene = beyer-15-ene
Other name(s): ent-kaurene synthase like 2; RcKSL4; OsKSL2; PpCPS/KS (ambiguous)
Systematic name: ent-copalyl-diphosphate diphosphate-lyase (cyclizing, ent-beyerene-forming)
Comments: The enzyme has been shown to occur in castor bean (Ricinus communis) and rice (Oryza sativa). ent-Beyerene is also a product of EC 4.2.3.19 (ent-kaurene synthase) of the moss Physcomitrella patens.
