tRNA-Pyl (pylT) gene from Methanosarcina barkeri str. Fusaro

this is the DNA coding sequence for the tRNA of pyrrolysine from the Archaea Methanosarcina barkeri str. Fusaro.

this tRNA is a part of the machinery that is used to incorporate pyrolysine into proteins in E.coli.

the tRNA synthetase that charges the tRNA with pyrrolysine can be found in biobrick BBa_k1223013.

the tRNA has the anticodon CUA - which means that the sense codon needed to incorporate pyrrolysine is TAG - the amber stop codon.

Design Notes

this is a part of the pyrrolysine incorporation machinery.

this tRNA is charged by pyrrolysyl-tRNA synthetase (pylS gene) to incorporate the amino acid pyro lysine. the tRNA has CUA anticodon that recognizes the TAG (UAG) codon on the mRNA during the translation process.

pylS CDS can be found in part BBa_K1223013.
