Peptide passports: Programmable import fuels novel protein building blocks Proteins with noncanonical amino acids can serve as precision tools and therapeutics, but their creation is often inefficient. In a recent Nature publication, Iype et al. engineered bacteria to ferry designer amino acids as peptide cargos, overcoming a major uptake bottleneck and enabling robust, scalable incorporation under routine culture conditions. http://dlvr.it/TPv3X8
