    Phenotypes of a mutant

  • increased autolysis [Pubmed|20400549]

    • The protein

    Catalyzed reaction/ biological activity

  • cleaves muropeptides derived from peptidoglycan, but not peptidoglycan itself [Pubmed|20400549]
  • Hydrolysis of terminal non-reducing N-acetyl-D-hexosamine residues in N-acetyl-beta-D-hexosaminides (according to UniProt)

    • Protein family

  • glycosyl hydrolase 3 family (single member, according to UniProt)

    • Structure

  • [PDB|3BMX] [Pubmed|20826810]

    • [SW|Localization]

  • secreted (with signal peptide), remains to some extent cell wall-associated [Pubmed|20400549]

    • Additional information

  • The gene is mis-annotated in KEGG as an ortholog of beta-N-acetylhexosaminidase EC 3.2.1.52. It is marked in MetaCyc as similar to beta-hexosaminidase. No EC annotation is available in Swiss-ProtSwiss-Prot.supporting the annotation is available. [Pubmed|19935659]
