CC -!- FUNCTION: Lysozymes have primarily a bacteriolytic function; those in
CC tissues and body fluids are associated with the monocyte-macrophage
CC system and enhance the activity of immunoagents.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=Hydrolysis of (1->4)-beta-linkages between N-acetylmuramic
CC acid and N-acetyl-D-glucosamine residues in a peptidoglycan and
CC between N-acetyl-D-glucosamine residues in chitodextrins.;
CC EC=3.2.1.17;
CC -!- SUBUNIT: Monomer.
CC -!- SUBCELLULAR LOCATION: Secreted.
CC -!- MISCELLANEOUS: Lysozyme C is capable of both hydrolysis and
CC transglycosylation; it shows also a slight esterase activity. It acts
CC rapidly on both peptide-substituted and unsubstituted peptidoglycan,
CC and slowly on chitin oligosaccharides.
CC -!- SIMILARITY: Belongs to the glycosyl hydrolase 22 family.
CC {ECO:0000255|PROSITE-ProRule:PRU00680}.
