FunFam 614: Peptidase, M4 (Thermolysin) family

There are 5 EC terms in this cluster

Please note: EC annotations are assigned to the full protein sequence rather than individual protein domains. Since a given protein can contain multiple domains, it is possible that some of the annotations below come from additional domains that occur in the same protein, but have been classified elsewhere in CATH.

Note: The search results have been sorted with the annotations that are found most frequently at the top of the list. The results can be filtered by typing text into the search box at the top of the table.

EC Term Annotations Evidence
Bacillolysin. [EC: 3.4.24.28]
Similar, but not identical, to that of thermolysin.
  • Variants of this enzyme have been found in species of Bacillus including B.subtilis, B.amyloliquefaciens, B.megaterium, B.mesentericus, B.cereus and B.stearothermophilus.
  • Belongs to peptidase family M4.
  • Formerly EC 3.4.24.4.

Aureolysin. [EC: 3.4.24.29]
Cleavage of insulin B chain with specificity similar to that of thermolysin, preferring hydrophobic P1' residues. Activates the glutamyl endopeptidase (EC 3.4.21.19) of Staphylococcus aureus.
  • Earlier confused with staphylokinase.
  • Belongs to peptidase family M4.
  • Formerly EC 3.4.24.4 and EC 3.4.99.22.

Thermolysin. [EC: 3.4.24.27]
Preferential cleavage: Xaa-|-Leu > Xaa-|-Phe.
  • A thermostable extracellular metalloendopeptidase containing four calcium ions.
  • Enzymes that may be species variants of thermolysin are reported from Micrococcus caseolyticus and Aspergillus oryzae.
  • Closely related but distinct enzymes are aeromonolysin, pseudolysin, bacillolysin, aureolysin and mycolysin.
  • Belongs to peptidase family M4.
  • Formerly EC 3.4.24.4.

Pseudolysin. [EC: 3.4.24.26]
Hydrolysis of proteins including elastin, collagen types III and IV, fibronectin and immunoglobulin A, generally with bulky hydrophobic group at P1'. Insulin B chain cleavage pattern identical to that of thermolysin, but specificity differs in other respects.
  • Causes tissue damage.
  • Belongs to peptidase family M4.
  • Formerly EC 3.4.24.4.

(8 more...)
Vibriolysin. [EC: 3.4.24.25]
Preferential cleavage of bonds with bulky hydrophobic groups in P2 and P1'. Phe at P1' is the most favored residue, which distinguished this enzyme from thermolysin.
  • Thermostable enzyme from Vibrio proteolyticus (formerly Aeromonas proteolytica).
  • Specificity related to, but distinct from, those of the thermolysin and Bacillus subtilis endopeptidase.
  • Belongs to peptidase family M4.
  • Formerly EC 3.4.24.4.
