Inhibited by Pseudomonas and E. coli Ivy proteins, this protein's active site requires the E35 and D52 acidic residues. Because it can be purified in large quantities, it was the first protein to be characterized at a 2-?gstrom level, by Lord David Phillips in 1965. In a classic example of convergent evolution, Alexander Fleming showed that the bacterial form of this enzyme has no sequence or structural elements in common with the hen egg variety, which is frequently used as a model source of peptides for inducing antibodies or cytotoxic T cell responses. It hydrolyzes 1-4-beta-glycosidic linkages in polysaccharides that make up chitin and bacterial cell walls, protecting the body surface of mammals and some insects from infections. For 10 points, name this enzyme, which along with defensins is released by the granules of white blood cells, and is also found in tears, saliva and inside lysosomes.
