Prenyltransferase

Prenyltransferases are a class of enzymes that transfer allylic prenyl groups to acceptor molecules. Prenyl transferases commonly refer to prenyl diphosphate synthases .

There are two classes of prenyltransferases, cis (or Z) and trans (or E), depending upon the stereo chemistry of the resulting products. Examples of trans-prenyltranferases include dimethylallyltranstransferase, and geranylgeranyl pyrophosphate synthase. Cis prenyltransferases include dehydrodolichol diphosphate synthase (involved in the production of dolichol precursors.
