Phage-assisted evolution can rapidly improve the efficiency and substrate specificity of orthogonal aminoacyl-tRNA synthetases. Furthermore, the crystal structure of the pyrrolysyl-tRNA synthetase N-terminal domain reveals the basis for these improvements and provides a structural rationale for orthogonality.
