Publication Abstract from PubMed

We solved the crystal structure of a functionally uncharacterized protein, HP0902, from Helicobacter pylori. Its structure demonstrated an all-beta cupin fold that cannot bind metal ions due to the absence of a metal-binding histidine that is conserved in many metallo-cupins. In contrast, isothermal titration calorimetry and NMR titration demonstrated that HP0902 is able to bind bacterial endotoxin lipopolysaccharides (LPS) through its surface-exposed loops, where metal-binding sites are usually found in other metallo-cupins. This report constitutes the first identification of an LPS-interacting protein, both in the cupin family and in H. pylori. Furthermore, identification of the ability of HP0902 to bind LPS uncovers a putative role for this protein in H. pylori pathogenicity.
