ent -Isokaurene synthase (EC 4.2.3.103, OsKSL5i , OsKSL6 ) is an enzyme with systematic name ent -copalyl-diphosphate diphosphate-lyase (cyclizing, ent -isokaurene-forming) .[ 1] [ 2] This enzyme catalyses the following chemical reaction
ent -copalyl diphosphate
⇌ ⇌ -->
{\displaystyle \rightleftharpoons }
ent -isokaurene + diphosphate
Two enzymes of the rice sub-species Oryza sativa ssp. indica, OsKSL5 and OsKSL6, produce ent-isokaurene.
