Exploration of GGTase-I substrate requirements. Part 2: Synthesis and biochemical analysis of novel saturated geranylgeranyl diphosphate analogs.

ABSTRACT: Protein prenylation is a type of post-translational modification that aids certain proteins in localizing to the plasma member where they activate cell signaling. To better understand the isoprenoid requirements and differences of FTase and GGTase-I, a series of saturated geranylgeranyl diphosphate analogs were synthesized and screened against both mammalian FTase and GGTase-I. Of our library of compounds, several analogs proved to be substrates of GGTase-I, with 11d having a krel=0.95 when compared to GGPP (krel=1.0).
