General annotation (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 By similarity.

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 structure

Monomer By similarity.

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 By similarity.

Sequence similarities

Belongs to the glycosyl hydrolase 22 family.
