Geranyl diphosphate 2 C methyltransferase

Geranyl diphosphate 2-C-methyltransferase (EC 2.1.1.255, SCO7701, GPP methyltransferase, GPPMT, 2-methyl-GPP synthase, MGPPS, geranyl pyrophosphate methyltransferase) is an enzyme with systematic name S-adenosyl-L-methionine:geranyl-diphosphate 2-C-methyltransferase. This enzyme catalyses the following chemical reaction

S-adenosyl-L-methionine + geranyl diphosphate ⇌ S-adenosyl-L-homocysteine + (E)-2-methylgeranyl diphosphate

This enzyme takes part in synthesis of 2-methylisoborneol.
