UniProt

Q08694 - LYSB_DROME

Protein

Lysozyme B

Gene

LysB

Organism
Drosophila melanogaster (Fruit fly)
Status
Reviewed - Annotation score: 3 out of 5- Experimental evidence at transcript leveli
  1. Functioni

    Unlikely to play an active role in the humoral immune defense. May have a function in the digestion of bacteria in the food.

    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.

    Expressioni

    Tissue specificityi

    Found in the midgut.

    Developmental stagei

    Maximal expression is found during the third larval instar, it drops to become undetectable in the late pupal stage. The expression in adults is similar to that of first and second larval instars.
