Protein farnesylation is an essential post-translational modification required for the function of numerous cellular proteins including the oncoprotein Ras. The farnesyl transferase (FTase) catalyzed reaction is unique because farnesyl diphosphate (FPP), the farnesyl group donor for the reaction, forms a significant portion of a target protein binding site. The major goal of this research was to exploit this unique property of the FTase reaction and determine if changing the structure of the farnesyl donor group would affect FTase protein targeting. A small library of structural analogues of FPP was synthesized. Michelis-Menten steady-state kinetic analyses and competition reactions were used to …
