FunFam 137545: Chitinase C1

There are 6 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.

Cellulose 1,4-beta-cellobiosidase (non-reducing end). [EC: 3.2.1.91]
Hydrolysis of (1->4)-beta-D-glucosidic linkages in cellulose and cellotetraose, releasing cellobiose from the non-reducing ends of the chains.
    		 2 A0A1D8G804 A0A1D8G804
    Endo-1,4-beta-xylanase. [EC: 3.2.1.8]
    Endohydrolysis of (1->4)-beta-D-xylosidic linkages in xylans.
      		 1 D1GET5
      Alkaline phosphatase. [EC: 3.1.3.1]
      A phosphate monoester + H(2)O = an alcohol + phosphate.
      • Active at a high pH optimum.
      • Wide specificity.
      • Also catalyzes transphosphorylations.
      • Some enzymes hydrolyze diphosphate (cf. EC 3.6.1.1).
      		 1 A0A178WW71
      Cellulase. [EC: 3.2.1.4]
      Endohydrolysis of (1->4)-beta-D-glucosidic linkages in cellulose, lichenin and cereal beta-D-glucans.
      • Will also hydrolyze 1,4-linkages in beta-D-glucans also containing 1,3-linkages.
      		 1 A0A0D0PU56
      Poly(3-hydroxybutyrate) depolymerase. [EC: 3.1.1.75]
      ((R)-3-hydroxybutanoate)(n) + H(2)O = ((R)-3-hydroxybutanoate)(n-1 to 5) + ((R)-3-hydroxybutanoate)(1-5).
      • Reaction also occurs with esters of other short-chain-length (C(1)- C(5)) hydroxyalkanoic acids (HA).
      • There are two types of polymers: native (intracellular) granules are amorphous and have an intact surface layer; denatured (extracellular) granules either have no surface layer or a damaged surface layer and are partially crystalline.
