Pyrrolysyl-tRNA Synthetase, an Aminoacyl-tRNA Synthetase for Genetic Code Expansion [PDF]
Genetic code expansion (GCE) has become a central topic of synthetic biology. GCE relies on engineered aminoacyl‐tRNA synthetases (aaRSs) and a cognate tRNA species to allow codon reassignment by co-translational insertion of non-canonical amino acids ...

Pyrrolysyl-tRNA synthetase variants reveal ancestral aminoacylation function [PDF]
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).

Expanding the genetic code: phage-driven evolution of pyrrolysyl-synthetase for site-specific incorporation of synthetic phenylalanine and tyrosine derivatives [PDF]
IntroductionPyrrolysyl-tRNA synthetase (PylRS) is a key enzyme for the site-specific incorporation of non-canonical amino acids (ncAAs) into proteins. However, its native form has a limited substrate scope.

tRNA shape is an identity element for an archaeal pyrrolysyl-tRNA synthetase from the human gut. [PDF]
Protein translation is orchestrated through tRNA aminoacylation and ribosomal elongation. Among the highly conserved structure of tRNAs, they have distinguishing features which promote interaction with their cognate aminoacyl tRNA synthetase (aaRS ...
