Accepted name: stemod-13(17)-ene synthase
Reaction: 9α-copalyl diphosphate = stemod-13(17)-ene + diphosphate

Glossary: syn-copalyl diphosphate = 9α-copalyl diphosphate
exo-stemodene = stemod-13(17)-ene
Other name(s): OsKSL11; stemodene synthase
Systematic name: 9α-copalyl-diphosphate diphosphate-lyase [stemod-13(17)-ene-forming]
Comments: This enzyme catalyses the committed step in the biosynthesis of the stemodane family of diterpenoid secondary metabolites, some of which possess mild antiviral activity. The enzyme also produces stemod-12-ene and stemar-13-ene as minor products.
