== Function ==
[https://www.uniprot.org/uniprot/PYLS_METMA PYLS_METMA] Catalyzes the attachment of pyrrolysine to tRNA(Pyl). Pyrrolysine is a lysine derivative encoded by the termination codon UAG (By similarity).

== Publication Abstract from PubMed ==
Three for two: By using a Methanosarcina mazei PylRS triple mutant (Y306G, Y384F, I405R) the incorporation of two new exo-norbornene-containing pyrrolysine analogues was achieved. X-ray crystallographic analysis led to the identification of the crucial structural elements involved in substrate recognition by the evolved synthetase.
