In enzymology a geranyltranstransferase (EC 2.5.1.10) is an enzyme that catalyzes the chemical reactiongeranyl diphosphate + isopentenyl diphosphate diphosphate + transtrans-farnesyl diphosphateThus the two substrates of this enzyme are geranyl diphosphate and isopentenyl diphosphate whereas its two products are diphosphate and transtrans-farnesyl diphosphate.This enzyme belongs to the family of transferases specifically those transferring aryl or alkyl groups other than methyl groups.
