What was done
The authors reviewed the principles, methods, and applications of genetic code reprogramming (GCR) in cell-free translation systems for the site-specific incorporation of non-canonical amino acids (ncAAs) and unnatural amino acids (UAAs) into target proteins.
What was found
The abstract provides a descriptive overview of how rewiring the genetic code expands the standard 20 amino acid repertoire to introduce novel physical, chemical, or biological properties into engineered proteins. No quantitative empirical findings, metrics, or comparative experimental data were reported in the abstract.
Why it matters
Incorporating ncAAs and UAAs enables protein engineers to generate customized proteins with novel functions and potential industrial, diagnostic, or therapeutic value.
Limits
The abstract describes a narrative book chapter/review and does not present original experimental protocols, quantitative efficiency rates, sample sizes, or comparative performance metrics.
