Ent-sandaracopimaradiene synthase explained

ent-sandaracopimaradiene synthase
Ec Number:	4.2.3.29

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.
