Pyrrolysyl-tRNA synthetase (PylRS) is a major tool in genetic code expansion using noncanonical amino acids, yet its structure and function are not completely understood. Here, we describe the crystal structure of the previously uncharacterized essential N-terminal domain of this unique enzyme from Methanosarcina mazei in complex with tRNAPyl. This structure explains why PylRS remains orthogonal in a broad range of organisms, from bacteria to humans. The structure also illustrates why tRNAPyl recognition by PylRS is anticodon-independent; the anticodon does not contact the enzyme. Then, using standard microbiol. culture equipment, we established a new method for laboratory evolution, PANCE, a noncontinuous counterpart of previously developed phage-assisted continuous evolution (PACE). With this method, we evolved novel PylRS variants with enhanced activity and amino acid specificity. Finally, we employed an evolved PylRS variant to determine its N-terminal domain structure and showed how its mutations improved PylRS activity in the genetic encoding of Nε-(tert-butoxycarbonyl)-
