IUBMB Enzyme Nomenclature


Accepted name: geranylgeranyl diphosphate synthase

Reaction: (2E,6E)-farnesyl diphosphate + isopentenyl diphosphate = diphosphate + geranylgeranyl diphosphate

Other name(s): geranylgeranyl-diphosphate synthase; geranylgeranyl pyrophosphate synthetase; geranylgeranyl-PP synthetase; farnesyltransferase; geranylgeranyl pyrophosphate synthase; farnesyltranstransferase (obsolete)

Systematic name: (2E,6E)-farnesyl-diphosphate:isopentenyl-diphosphate farnesyltranstransferase

Comments: Some forms of this enzyme will also use geranyl diphosphate and dimethylallyl diphosphate as donors; it will not use larger prenyl diphosphates as efficient donors.
