Stemar-13-ene synthase
Stemar-13-ene synthase (EC 4.2.3.33, OsDTC2, OsK8, OsKL8, OsKS8, stemarene synthase, syn-stemar-13-ene synthase) is an enzyme with systematic name 9alpha-copalyl-diphosphate diphosphate-lyase (stemar-13-ene-forming).[1][2] This enzyme catalyses the following chemical reaction
- 9alpha-copalyl diphosphate stemar-13-ene + diphosphate
