WebApr 25, 2024 · Why did PylRS identity switch to a G73 discriminator base? A possible reason might be the increased substrate specificity conferred by the G73 discriminator … WebThe Methanosarcina mazei pyrrolysyl-tRNA synthetase (PylRS)⋅tRNAPyl pair can be used to incorporate non-canonical amino acids (ncAAs) into proteins at installed amber stop codons. Although engineering of the PylRS active site generates diverse binding pockets, the substrate ranges are found similar in charging lysine and phenylalanine analogs.
