Unraveling the Structure and Mechanism of the MST(ery) Enzymes.


ABSTRACT: The menaquinone, siderophore, and tryptophan (MST) enzymes transform chorismate to generate precursor molecules for the biosynthetic pathways defined in their name. Kinetic data, both steady-state and transient-state, and X-ray crystal structures indicate that these enzymes are highly conserved both in mechanism and in structure. Because these enzymes are found in pathogens but not in humans, there is considerable interest in these enzymes as drug design targets. While great progress has been made in defining enzyme structure and mechanism, inhibitor design has lagged behind. This review provides a detailed description of the evidence that begins to unravel the mystery of how the MST enzymes work, and how that information has been used in inhibitor design.
