An Unnatural Amino Acid-Regulated Growth Controller Based on Informational Disturbance [PDF]
We designed a novel growth controller regulated by feeding of an unnatural amino acid, Nε-benzyloxycarbonyl-l-lysine (ZK), using a specific incorporation system at a sense codon. This system is constructed by a pair of modified pyrrolisyl-tRNA synthetase

A linear DNA template-based framework for site-specific unnatural amino acid incorporation [PDF]
Site-specific incorporation of unnatural amino acids (UNAAs) into proteins using an orthogonal translation system (OTS) has expanded the scope of protein-coding chemistry. The key factor affecting UNAA embedding efficiency is the orthogonality of the OTS.
