• To highlight the role of high-throughput screening in these advancements.

Main Methods:

• Engineering aminoacyl-tRNA synthetases (aaRSs) and tRNAs with novel selection methods.
• Improving protein translation machinery and cellular components for alternative genetic codes.
• Utilizing discovery platforms for high-throughput screening of ncAA-containing proteins.

Main Results:

• Novel selection methods improve ncAA incorporation efficiency and selectivity.
• Engineering cellular components enhances ncAA incorporation.
• Discovery platforms yield innovative binding ligands and enzymes with enhanced functionalities.
