Chains	Enzyme Name	Description	Catalytic Residues
A	geranyltranstransferase M-CSA #253	Geranyltranstransferase is a member of the Isoprenoid Synthase Type I superfamily. It catalyses the metal-dependent formation of (2E,6E)-farnesyl diphosphate from geranyl diphosphate + isopentenyl diphosphate. It is known that the residue at the fifth position before the first DDxxD motif [PMID:12135472], in this case a phenylalanine, is responsible for determining product chain length.
