Using an amber suppression-based noncanonical amino acid (ncAA) mutagenesis approach, the chemical space in phage display can be significantly expanded for drug discovery. In this work, we demonstrate the development of a novel helper phage, CMa13ile40, for continuous enrichment of amber obligate phage clones and efficient production of ncAA-containing phages. CMa13ile40 was constructed by insertion of a Candidatus Methanomethylophilus alvus pyrrolysyl-tRNA synthetase/PylT gene cassette into a helper phage genome.

Phage-assisted, active site-directed ligand evolution (PADLE) is a recently developed technique that uses an amber codon-encoded noncanonical amino acid (ncAA) as an anchor to direct phage-displayed peptides to a target for an enhanced ligand identification process. 2-Amino-8-oxodecanoic acid (Aoda) is a ketone-containing ncAA residue in the macrocyclic peptide natural product apicidin that is a pan-inhibitor of Zn -dependent histone deacetylases (HDACs). Its ketone serves as an anchoring point to coordinate the catalytic zinc ion in HDACs.
