Ent-cassa-12,15-diene synthase

Ent-cassa-12,15-diene synthase (EC 4.2.3.28, OsDTC1, OsKS7) is an enzyme with systematic name ent-copalyl-diphosphate diphosphate-lyase (ent-cassa-12,15-diene-forming).[1] This enzyme catalyses the following chemical reaction

ent-copalyl diphosphate ent-cassa-12,15-diene + diphosphate
