    The interactions between the polyanionic ligands phosphate and sulphate and the type II dehydroquinases from Streptomyces coelicolor and Mycobacterium tuberculosis have been characterised using a combination of structural and kinetic methods. From both approaches, it is clear that interactions are more complex in the case of the latter enzyme. The data provide new insights into the differences between the two enzymes in terms of substrate recognition and catalytic efficiency and may also explain the relative potencies of rationally designed inhibitors. An improved route to the synthesis of the substrate 3-dehydroquinic acid (dehydroquinate) is described.
