Ent-sandaracopimaradiene synthase

Ent-sandaracopimaradiene synthase (EC 4.2.3.29, OsKS10, ent-sandaracopimara-8(14),15-diene synthase) is an enzyme with systematic name ent-copalyl-diphosphate diphosphate-lyase (ent-sandaracopimara-8(14),15-diene-forming).^[1]^[2] This enzyme catalyses the following chemical reaction

ent-copalyl diphosphate

\rightleftharpoons

ent-sandaracopimara-8(14),15-diene + diphosphate

ent-Sandaracopimaradiene is a precursor of the rice oryzalexins A-F.
