Glossary: 3-methylbut-3-en-1-yl = isopentenyl (ambiguous)
prenyl = 3-methylbut-2-en-1-yl = dimethylallyl (ambiguous)
Other name(s): geranyl-diphosphate synthase; prenyltransferase; dimethylallyltransferase; DMAPP:IPP-dimethylallyltransferase; (2E,6E)-farnesyl diphosphate synthetase; diprenyltransferase; geranyl pyrophosphate synthase; geranyl pyrophosphate synthetase; trans-farnesyl pyrophosphate synthetase; dimethylallyl-diphosphate:isopentenyl-diphosphate dimethylallyltranstransferase
Systematic name: prenyl-diphosphate:3-methylbut-3-en-1-yl-diphosphate prenyltranstransferase
Comments: This enzyme will not accept larger prenyl diphosphates as efficient donors.
