2.5.1.59 | additional information | Rattus norvegicus | the enzyme modifies proteins by attaching a 20-carbon isoprenoid group to a cysteine residue near the C-terminus of a target protein. The enzyme requires a C-terminal Ca1a2X sequence on its substrates, with the a1, a2, and X residues serving as substrate-recognition elements for GGTase-I. Crystallographic structures of rat GGTase-I show a tightly packed and hydrophobic a2 residue binding pocket, consistent with a preference for moderately sized a2 residues in GGTase-I substrates, peptide substrate structure-activity relationship, overview.
