Lysozyme occurs in many tissues of invertebrate and vertebrate animals. it is found in milk, blood serum and various secretions (saliva, nasal mucus and tears). it also occurs in some moulds and in the latex of certain plants. lysozyme from human milk was studied in some detail and is very similar to the hen enzyme. lysozyme is a glycosidase which dissolves various bacterial cell walls [particularly gram-positive bacteria (which have surface lipoproteins) to give spheroblasts, and various gram-negative bacteria in the presence of edta in hypotonic solutions, or non-ionic detergents].
