Dimethylallyltranstransferase

Dimethylallyltranstransferase is an enzyme which converts dimethylallylpyrophosphate and isopentenyl pyrophosphate into farnesylpyrophosphate. It is also commonly referred to as farnesylpyrophosphate synthase or farnesyldiphosphate synthase.

Pyrophosphate is also involved, both as a reactant and product. Geranylpyrophosphate is created in an intermediate step.
