    The protein

    Catalyzed reaction/ biological activity

  • the C-terminal toxic domain has RNase activity (cleaves tRNAs) [Pubmed|23572593]

    • Protein family

  • RHS/WapA nuclease family (single member, according to UniProt)

    • [SW|Domains]

  • cell wall binding domain as retention signal
  • C-terminal toxic domain with RNase activity (cleaves tRNAs) [Pubmed|23572593]
  • Has two ligand-binding domains; the N-terminus has three 101 AA repeats which are responsible for cell wall binding; the C-terminus consists of two blocks of residues with a conserved motif repeated 31 times (according to UniProt)

    • Effectors of protein activity

  • [protein|C7400733DB8835A204A7FF26C87A92A15C5F318C|WapI] inhibits the toxic activity of [protein|BBC06DA57CAC2B2378763E0839C6C31AFBEA0417|WapA] [Pubmed|23572593]

    • [SW|Localization]

  • extracellular (signal peptide), cell wall binding domain as retention signal, major constituent of the secretome [Pubmed|18957862]
