Q9PU28 - LYSC_PSEMX

Protein

Lysozyme C

Gene

lys

Organism
Psetta maxima (Turbot) (Pleuronectes maximus)
Status
Reviewed - Annotation score: 3 out of 5- Experimental evidence at transcript leveli
  1. 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.PROSITE-ProRule annotation

    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.

    Miscellaneousi

    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.
