FunFam 118: Probable bifunctional chitinase/lysozyme

There are 2 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
Chitinase. [EC: 3.2.1.14]
Random endo-hydrolysis of N-acetyl-beta-D-glucosaminide (1->4)-beta- linkages in chitin and chitodextrins.
  • The enzyme binds to chitin and randomly cleaves glycosidic linkages in chitin and chitodextrins in a non-processive mode, generating chitooligosaccharides and free ends on which exo-chitinases and exo- chitodextrinases can act.
  • Activity is greatly stimulated in the presence of EC 1.14.99.53, which attacks the crystalline structure of chitin and makes the polymer more accesible to the chitinase.
  • Cf. EC 3.2.1.202.

Lysozyme. [EC: 3.2.1.17]
Hydrolysis of (1->4)-beta-linkages between N-acetylmuramic acid and N-acetyl-D-glucosamine residues in a peptidoglycan and between N-acetyl- D-glucosamine residues in chitodextrins.
  • Cf. EC 3.2.1.14.
