Abstract
Pyrrolysyl-tRNA synthetase (PylRS) is a class IIc aminoacyl-tRNA synthetase that is related to phenylalanyl-tRNA synthetase (PheRS). Genetic selection provided PylRS variants with a broad range of specificity for diverse non-canonical amino acids (ncAAs). One variant is a specific phenylalanine-incorporating enzyme. Structural models of the PylRSamino acid complex show that the small pocket size and π-interaction play an important role in specific recognition of Phe and the engineered PylRS active site resembles that of Escherichia coli PheRS.Entities:
