Binds to a large surface of Tse2 and thereby occludes the active site to specifically inhibits Tse2.<ref>PMID:22310046</ref> <ref>PMID:22511866</ref> <ref>PMID:26749446</ref>

Tse2 is a cytoactive toxin secreted by a type six secretion apparatus of Pseudomonas aeruginosa. The Tse2 toxin naturally attacks a target in the cytoplasm of bacterial cells, and can cause toxicity if artificially introduced into eukaryotic cells. The X-ray crystal structure of the complex of Tse2 and its cognate immunity protein Tsi2 revealed a heterotetrameric structure with an extensive binding interface. Structural identity was found between Tse2 and NAD-dependent enzymes, especially ADP-ribosylating toxins, which facilitated the identification of the Tse2 active site and revealed it to be occluded upon binding the inhibitor Tsi2. The structural identity shared with NAD-dependent enzymes, including conserved catalytic residues, suggests that the mechanism of Tse2 toxicity may be NAD dependent.
