    Phenotypes of a mutant

  • increased thermotolerance due to increased stabiliy of [protein|2C6386E9A63F410558D168798D077DF91590F454|Spx] and thus increased expression of ''[gene|4E5C84FDC8FE2FEFF47306C91ECAB7F17D3E38E9|trxA]'' [Pubmed|24417481]
  • the mutation suppresses the heat sensitivity of spores overexpressing ''[gene|85DE3CB6CDA61C141C6030367C0A13BB642160B9|cmpA]'' [Pubmed|26387458]
  • non-motile [Pubmed|27014237]

    • The protein

    Catalyzed reaction/ biological activity

  • Hydrolysis of proteins to small peptides in the presence of ATP and magnesium. Alpha-casein is the usual test substrate. In the absence of ATP, only oligopeptides shorter than five residues are hydrolyzed (such as succinyl-Leu-Tyr-|-NHMec, and Leu-Tyr-Leu-|-Tyr-Trp, in which cleavage of the -Tyr-|-Leu- and -Tyr-|-Trp bonds also occurs) (according to UniProt)
  • antibiotic-activated [protein|CB06A70DE7462CEB7AF5D8C28943C878DD56DE1A|ClpP] unfolds [protein|41872E2EF00C79918DD077F2EF78F37E24FEB110|FtsZ] for N-terminal degradation [pubmed|32605984]

    • Protein family

  • Peptidase S14 family (with [protein|A16C6515D185E3A268D57D77F28EF7EF9AF9FE05|TepA], according to UniProt)

    • Modification

  • phosphorylated on Arg-13 [Pubmed|22517742]

    • Effectors of protein activity

  • the novel antibiotic ADEP (acyldepsipeptides) dysregulates [protein|CB06A70DE7462CEB7AF5D8C28943C878DD56DE1A|ClpP] activity and allows [protein|41872E2EF00C79918DD077F2EF78F37E24FEB110|FtsZ] degradation in the absence of an ATPase subunit ([protein|86A2F2F65290F4471D6FD03B694821C66C180D8A|ClpC], [protein|8C5B14FE5E03427F9A598C75D4081FA0D6696299|ClpE], or [protein|297F53DAD3351E0C55108DD2C93B78FFB174438C|ClpX]) [Pubmed|21969594]

    • Structure

  • [PDB|3KTG] [Pubmed|20305655]

    • [SW|Localization]

  • cytoplasmic polar clusters, excluded from the nucleoid, induced clustering upon heat shock, colocalization with [protein|297F53DAD3351E0C55108DD2C93B78FFB174438C|ClpX], [protein|86A2F2F65290F4471D6FD03B694821C66C180D8A|ClpC] and [protein|8C5B14FE5E03427F9A598C75D4081FA0D6696299|ClpE] [Pubmed|18786145,18689473]
