Enzymatic thermal switch: The bacterial 4-methylideneimidazol-5-one (MIO) dependent enzymes AdmH and EncP are shown to display remarkable thermal bifunctionality: they act as mutases (blue graph) at lower temperatures but with lyase (red graph) activity predominant at higher temperatures. This temperature-dependent switch in enzyme class also explains how these two similar enzymes can fulfill different catalytic functions in secondary metabolisms.
