Abstract excerpt
Posttranslational modifications are essential for the proper function of a number of proteins in the cell. One such modification, the covalent attachment of a single isoprenoid lipid (prenylation), is carried out by the CaaX prenyltransferases, protein farnesyltransferase (FTase) and protein geranylgeranyltransferase type-I (GGTase-I). Substrate proteins of these two enzymes are involved in a variety of cellular...
