[1]	PROTEIN SEQUENCE. STRAIN=Kaki duck; TISSUE=Egg white; PubMed=5138644 [NCBI, ExPASy, EBI, Israel, Japan] Hermann J., Jolles J., Jolles P.; "Multiple forms of duck-egg white lysozyme. Primary structure of two duck lysozymes."; Eur. J. Biochem. 24:12-17(1971).

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.
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].
