Phenotypes of a mutant
increased autolysis [Pubmed|20400549]The protein
Catalyzed reaction/ biological activity

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]Expression and Regulation
