Various mechanisms have evolved by which bacteria can evade this bactericidal enzyme, one being the production of lysozyme inhibitors. MliC (membrane bound lysozyme inhibitor of c-type lysozyme) of E. coli and Pseudomonas aeruginosa, possess lysozyme inhibitory activity and confer increased lysozyme tolerance upon expression in E. coli [1]. Structural analyses show that the invariant loop of MliC plays a crucial role in the inhibition of the lysozyme by its insertion into the active site cleft of the lysozyme, where the loop forms hydrogen and ionic bonds with the catalytic residues [2].
