Protein

Peptidoglycan-recognition protein SB1

Gene

PGRP-SB1

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

Functioni

N-acetylmuramyl-L-alanine amidase involved in innate immunity by degrading bacterial peptidoglycans (PGN), preferentially DAP-type PGNs. Probably plays a scavenger role by digesting biologically active PGN into biologically inactive fragments.1 Publication

Catalytic activityi

Hydrolyzes the link between N-acetylmuramoyl residues and L-amino acid residues in certain cell-wall glycopeptides.
