‘Three distinct protein prenyltransferases have been identified to date (reviewed in [3]), which can be classified into two functional classes: the CAAX prenyltransferases, farnesyltransferase and geranylgeranyltransferase type I (GGTase-I), and the Rab geranylgeranyltransferase or GGTase type I1 (Rab GGTase). CAAX prenyltransferases recognize a distinct motif at the C-terminus of intracellular protein substrates. The motif is designated CAAX, where C is cysteine, A is an aliphatic amino acid and X is any amino acid. The CAAX sequence is the primary determinant for transferase binding to a protein substrate. If the last amino acid in the CAAX sequence is a methionine or serine, the protein is a substrate of farnesyltransferase, whereas if it is a leucine it becomes a substrate
