Comments
  • FUNCTION: 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.
  • CATALYTIC ACTIVITY: 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.
  • COFACTOR: Binds 1 calcium ion per subunit.
  • SUBUNIT: Monomer.
  • MISCELLANEOUS: Lysozyme C is capable of both hydrolysis and transglycosylation; it shows also a slight esterase activity. It acts rapidly on both peptide-substituted and unsubstituted peptidoglycan, and slowly on chitin oligosaccharides.
  • SIMILARITY: Belongs to the glycosyl hydrolase 22 family [view classification].
