FunFam 2: Microbial collagenase

There are 1 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
Microbial collagenase. [EC: 3.4.24.3]
Digestion of native collagen in the triple helical region at Xaa-|-Gly bonds. With synthetic peptides, a preference is shown for Gly at P3 and P1', Pro and Ala at P2 and P2', and hydroxyproline, Ala or Arg at P3'.
  • Six species of metalloendopeptidase acting on native collagen can be isolated from the medium of Clostridium histolyticum.
  • Class I has forms alpha (68 kDa), beta (115 kDa) and gamma (79 kDa); class II has delta (100 kDa), epsilon (110 kDa) and zeta (125 kDa).
  • The two classes are immunologically crossreactive, but have significantly different sequences, and different specificities such that their actions on collagen are complementary.
  • The enzymes also act as peptidyl-tripeptidases.
  • Variants of the enzyme have been purified from Bacillus cereus, Empedobacter collagenolyticum, Pseudomonas marinoglutinosa, and species of Vibrio, Vibrio B-30 (ATCC 21250) and V.alginolyticus (previously Achromobacter iophagus).
  • Also known from Streptomyces sp.
  • Belongs to peptidase family M9.
  • Formerly EC 3.4.4.19, EC 3.4.24.8 and EC 3.4.99.5.
