Its function is associated with protecting M. oryzae from the host immune response in plants. To provide the structural basis of how MGG_03307 protects the fungus, crystal structures of its CVNH-LysM module were determined in the absence and presence of GlcNAc-containing cell wall chitin constituents, which can act as pathogen-associated molecular patterns. Our structures revealed that glycan binding is accompanied by a notable conformational change in the LysM domain and that GlcNAc3 and GlcNAc4 are accommodated similarly. GlcNAc5 and GlcNAc6 interact with the LysM domain in multiple conformations, as evidenced by solution nuclear magnetic resonance studies. No dimerization of MoCVNH3 via its LysM domain was observed upon binding to GlcNAc6, unlike in multiple LysM domain-containing proteins. Importantly, we define a specific consensus binding mode for the recognition of GlcNAc oligomers by single LysM domains.
