Struktur und Reaktionsmechanismus der Pyrrolysinsynthase (PylD)

Felix Quitterer, Philipp Beck, Adelbert Bacher, Michael Groll

Research output: Contribution to journalArticlepeer-review


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.
