ncAA Incorporated Peptide Library Development
Creating diverse libraries of peptides containing ncAAs at defined positions for high-throughput screening to identify leads with novel binding or functional properties.
Genetic code expansion (GCE) technology represents a transformative approach in molecular biology, enabling the site-specific incorporation of non-canonical amino acids (ncAAs) into proteins and peptides. The ncAA-incorporated peptide engineering focuses on the rational design and production of peptides containing precisely positioned ncAAs to confer novel properties, such as enhanced stability, unique conjugation handles, or new biological activities. As a pioneering biotech leader and trusted partner in preclinical services, our company facilitates this area's progress by providing a proprietary GCEngine platform. This service supports the entire development lifecycle, from identifying novel orthogonal pairs to applying ncAA-incorporated peptides, offering researchers precise control over molecular structure and function.
ncAA incorporated peptide engineering represents a specialized application of GCE technology aimed at the creation of next-generation peptide-based molecules. This process involves the co-translational insertion of chemically diverse ncAAs at predetermined sites within a peptide sequence during biosynthesis. This precise modification allows for the introduction of functionalities not found in natural amino acids, such as bio-orthogonal chemical groups (e.g., azides, alkynes), post-translational modification mimics, fluorophores, or moieties that modulate pharmacokinetic properties. The result is a class of engineered peptides with tailor-made characteristics for applications in research and drug development.
