Abstract

Two's company: Using a wild-type or evolved PylRS-pylTUUA pair to suppress ochre mutation and an evolved MjTyrRS-Mjequation image 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 14; GFP=green-fluorescent protein).
