== Function == | |||
[https://www.uniprot.org/uniprot/PYLD_METBF PYLD_METBF] Catalyzes the ultimate step of the pyrrolysine biosynthesis pathway by converting the isopeptide (3R)-3-methyl-D-ornithyl-N(6)-L-lysine to the 22nd proteinogenic amino acid (PubMed:24916332). Is able to use surrogate substrates such as (3R)-D-ornithyl-N(6)-L-lysine in vitro (PubMed:23720358, PubMed:24916332).<ref>PMID:23720358</ref> <ref>PMID:24916332</ref> | |||

== Publication Abstract from PubMed == | |||
The final step in the biosynthesis of the 22nd genetically encoded amino acid, pyrrolysine, is catalyzed by PylD, a structurally and mechanistically unique dehydrogenase. This catalyzed reaction includes an induced-fit mechanism achieved by major structural rearrangements of the N-terminal helix upon substrate binding. Different steps of the reaction trajectory are visualized by complex structures of PylD with substrate and product. | |||
