Lanthipeptide synthetases katalyseren multistep reacties tijdens de biosynthese van peptide natuurlijke producten. Hier beschrijven we een continue, bottom-up, waterstof-deuterium uitwisseling massaspectrometrie (HDX-MS) workflow die kan worden gebruikt om de conformationele dynamiek van lanthipeptide synthetases te bestuderen, evenals andere vergelijkbare enzymen die betrokken zijn bij peptide natuurlijke productbiosynthese.
