  • PubMed Abstract: 

    Legionella pneumophila is a pathogen causing severe pneumonia in humans called Legionnaires' disease. Lem22 is a previously uncharacterized effector protein conserved in multiple Legionella strains. Here, we report the crystal structure of Lem22 from the Philadelphia strain, also known as lpg2328, at 1.40 Å resolution. The structure shows an up-and-down three-helical bundle with a significant structural similarity to a number of protein-binding domains involved in apoptosis and membrane trafficking. Sequence conservation identifies a putative functional site on the interface of helices 2 and 3. The structure is an important step toward a functional characterization of Lem22.
