SYSTEMATIC NAME
IUBMB Comments
9alpha-copalyl-diphosphate diphosphate-lyase [stemod-13(17)-ene-forming]
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.
