ID 4.2.3.99 DE labdatriene synthase. CA 9alpha-copalyl diphosphate = (12E)-9alpha-labda-8(17),12,14-triene + CA diphosphate. CC -!- The enzyme from rice (Oryza sativa), expressed in Escherichia coli, CC also produces ent-sandaracopimara-8(14),15-diene from ent-copalyl CC diphosphate, another naturally occurring copalyl isomer in rice (cf. CC EC 4.2.3.29). DR Q2QQJ5, KSL10_ORYSJ; //
