Selection of Myristoyltransferase Inhibitor Phages from Phage Display Random Peptide Library

Through screening library with either immobilized or coated enzymes, we selected disease-related myristoyltransferase inhibitor phages from phage display random peptide library. After high-affinity bound phages were obtained, they were subjected to in vitro NMT inhibition assay to identify inhibitor phages. The results of DNA sequencing, peptide sequence deducing and sequence aligning of the 16 inhibitor phages suggested that the sequences of inhibitor peptides obtained by the two separate screening methods appeared overlapping, and included a consensus motif PX(0-3)H/R or H/RX(0-3)R, in which X represented a non-specific amino acid.
