Expanding the genetic code of organisms by incorporating non‐canonical amino acids (ncAAs) into target proteins through the suppression of stop codons in vivo has profoundly impacted how we perform protein modification or detect proteins and their interaction partners in their native environment. Yet, with genetic code expansion strategies maturing over the past 15 years, new applications that make use – or indeed repurpose – these techniques are beginning to emerge. This concept article highlights three of these developments: (1) the incorporation of ncAAs for the biosynthesis and selection of bioactive macrocyclic peptides with novel ring architectures, (2) synthetic biocontainment strategies based on the addiction of microorganisms to ncAAs, and (3) enzyme design strategies, in which ncAAs with unique functionalities enable the catalysis of new‐to‐nature reactions. Key advances in all three areas are presented and potential future applications discussed.
