RL   Submitted (MAR-1995) to the EMBL/GenBank/DDBJ databases.
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   -!- SIMILARITY: Belongs to the glycosyl hydrolase 22 family.
CC       {ECO:0000255|PROSITE-ProRule:PRU00680}.
