Machine Learning Enables Prediction of Pyrrolysyl-tRNA Synthetase Substrate Specificity

open access: yesACS Synthetic Biology, 2023
Knowledge about the substrate scope for a given enzyme is informative for elucidating biochemical pathways and also for expanding applications of the enzyme.

Directed Evolution of the Methanosarcina barkeri Pyrrolysyl tRNA/aminoacyl tRNA Synthetase Pair for Rapid Evaluation of Sense Codon Reassignment Potential

open access: yesInternational Journal of Molecular Sciences, 2021
Genetic code expansion has largely focused on the reassignment of amber stop codons to insert single copies of non-canonical amino acids (ncAAs) into proteins.

Pyrrolysine analogues as substrates for pyrrolysyl-tRNA synthetase [PDF]

open access: yesFEBS Letters, 2006
In certain methanogenic archaea a new amino acid, pyrrolysine (Pyl), is inserted at in-frame UAG codons in the mRNAs of some methyltransferases. Pyl is directly acylated onto a suppressor tRNAPyl by pyrrolysyl-tRNA synthetase (PylRS).

The amino-terminal domain of pyrrolysyl-tRNA synthetase is dispensable in vitro but required for in vivo activity [PDF]

open access: yesFEBS Letters, 2007
Pyrrolysine (Pyl) is co-translationally inserted into a subset of proteins in the Methanosarcinaceae and in Desulfitobacterium hafniense programmed by an in-frame UAG stop codon. Suppression of this UAG codon is mediated by the Pyl amber suppressor tRNA,
