A Facile System for Genetic Incorporation of Two Different Noncanonical Amino Acids into One Protein in Escherichia coli

Two's company: Using a wild-type or evolved PylRS-pylTUUA pair to suppress ochre mutation and an evolved MjTyrRS-Mj pair to suppress amber mutation, two different noncanonical amino acids (NAAs) have been concomitantly incorporated into one protein in E. coli with high efficiency (see picture, with NAAs 1–4; GFP=green-fluorescent protein).
