2.1.1.255 | metabolism | geranyl diphosphate C-methyltransferase is the methyltransferase that modifies an acyclic isoprenoid diphosphate, geranyl diphosphate, to yield a noncanonical acyclic allylic diphosphate product, 2-methylgeranyl diphosphate, which serves as the substrate for a subsequent cyclization reaction catalyzed by a terpenoid cyclase, methylisoborneol synthase | Streptomyces coelicolor |
