Protein
Bifunctional autolysin
Gene
atl, SERP0636
Organism
Staphylococcus epidermidis (strain ATCC 35984 / RP62A)
Status
Reviewed - Annotation score: 4 out of 5 - Protein inferred from homologyi

Functioni

Endohydrolysis of the di-N-acetylchitobiosyl unit in high-mannose glycopeptides and glycoproteins containing the -[(Man)5(GlcNAc)2]-Asn structure. One N-acetyl-D-glucosamine residue remains attached to the protein; the rest of the oligosaccharide is released intact. Cleaves the peptidoglycan connecting the daughter cells at the end of the cell division cycle, resulting in the separation of the two newly divided cells. Acts as an autolysin in penicillin-induced lysis By similarity.

Catalytic activityi

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