SpoIID (Stage II Sporulation Protein D) is a Lytic Transglycosylase (LT) essential for sporulation. The LT-superfamily is a potential drug target because they are active in essential bacterial processes involving the peptidoglycan (PGN), which is unique to bacteria. However, the absence of structural information for the sporulation specific LT enzymes has hindered mechanistic understanding of SpoIID. Here, we report the first crystal structures with and without ligands of the SpoIID family from two community relevant spore-forming pathogens, Bacillus anthracis and Clostridium difficile. The structures allow us to visualize the overall architecture, characterize the substrate recognition model, identify critical residues and provide the structural basis for catalysis by this new family of enzymes.
