    Phenotypes of a mutant

  • cell separation defect, this is increased by a ''[gene|321F248C22D7283C0F3323F1F4069E36F8D7FE6C|lytE]'' mutation [Pubmed|23855774]

    • The protein

    Catalyzed reaction/ biological activity

  • cleaves the peptide bond between D-Glu (position 2 in the peptioglycan peptide) and m-diamino pimelic acid (position 3) [Pubmed|18266855]
  • degradation of gamma-polyglutamic acid [pubmed|29458655]

    • Protein family

  • [SW|Peptidase C40 family] (according to UniProt)

    • [SW|Domains]

  • contains five N-acetylglucosamine-polymer-binding [SW|LysM domain]s [Pubmed|18430080]
  • C-terminal D,L-endopeptidase domain ([SW|NlpC/P60 domain]) [pubmed|29458655,22139507]
  • 5 [SW|LysM domain]s (aa 27-70, aa 92-135, aa 174-217, aa 240-283, aa 307-350) (according to UniProt)

    • Effectors of protein activity

  • both enzymatic activities are inhibited by interaction with [protein|0CA55371306D4BD768CFA82027DCB4D581BCCB87|IseA] [pubmed|29458655]

    • Structure

  • [PDB|4XCM] (from Thermus thermophilus, 31% identity) [pubmed|25760608]

    • [SW|Localization]

  • secreted (according to Swiss-Prot)
  • localizes to cell septa and poles on the vegetative cell surface, this depends on the presence of lipoteichoic acids ([protein|418900B6DBDF3EF300C930B0C75E31B939F3CE00|LtaS]) [Pubmed|25288647,22139507]
