Ligands: MG, MSE, NA, NAD Resources: FirstGlance, OCA, PDBe, RCSB, PDBsum, ProSAT Function Q46E80_METBF 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.
