==Overview==

The crystal structures of the type II dehydroquinase (DHQase) from, Helicobacter pylori in complex with three competitive inhibitors have been, determined. The inhibitors are the substrate analogue 2,3-anhydroquinate, (FA1), citrate, and an oxoxanthene sulfonamide derivative (AH9095)., Despite the very different chemical nature of the inhibitors, in each case, the primary point of interaction with the enzyme is via the residues that, bind the C1 functionalities of the substrate, 3-dehydroquinate, i.e., N76, H102, I103, and H104. The DHQase/AH9095 complex crystal structure shows, that sulfonamides can form a scaffold for nonsubstrate-like inhibitors and, identifies a large conserved hydrophobic patch at the entrance to the, active site as a locus that can be exploited in the development of new, ligands.
