Lysozymes have primarily a bacteriolytic function; those in tissues and body fluids are associated with the monocyte-macrophage system and enhance the activity of immunoagents. Hydrolysis of (1->4)-beta-linkages between N-acetylmuramic acid and N-acetyl-D-glucosamine residues in a peptidoglycan and between N-acetyl-D-glucosamine residues in chitodextrins. 3 allelic variants of cecropia moth lysozyme have been found. The sequence shown is that of lysozyme 1. Belongs to the glycosyl hydrolase 22 family.
