Protein

Lysozyme

Gene
N/A
Organism
Bombyx mori (Silk moth)
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

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. Active against E.coli and M.luteus.PROSITE-ProRule annotation1 Publication

Catalytic activityi

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.
