Functional Families

Overview of the Structural Clusters (SC) and Functional Families within this CATH Superfamily. Clusters with a representative structure are represented by a filled circle.

Superfamily EC Annotations

Note: the EC figure is not being displayed for this superfamily as there are more than 100 different EC terms.

There are 8 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
5-oxoprolinase (ATP-hydrolyzing). [EC: 3.5.2.9]
ATP + 5-oxo-L-proline + 2 H(2)O = ADP + phosphate + L-glutamate.

    4-deoxy-4-formamido-L-arabinose-phosphoundecaprenol deformylase. [EC: 3.5.1.n3]
    4-deoxy-4-formamido-beta-L-arabinose di-trans,poly-cis-undecaprenyl phosphate + H(2)O = 4-amino-4-deoxy-alpha-L-arabinose di-trans,poly- cis-undecaprenyl phosphate + formate.

      Chitin disaccharide deacetylase. [EC: 3.5.1.105]
      N,N'-diacetylchitobiose + H(2)O = N-acetyl-beta-D-glucosaminyl-(1->4)-D- glucosamine + acetate.
      • Chitin oligosaccharide deacetylase is a key enzyme in the chitin catabolic cascade of chitinolytic Vibrio strains.
      • Besides being a nutrient, the heterodisaccharide product 4-O- (N-acetyl-beta-D-glucosaminyl)-D-glucosamine is a unique inducer of chitinase production in Vibrio parahemolyticus.
      • In contrast to EC 3.5.1.41 this enzyme is specific for the chitin disaccharide.
      • It also deacetylates the chitin trisaccharide with lower efficiency.
      • No activity with higher polymers of GlcNAc.

      Chitin deacetylase. [EC: 3.5.1.41]
      Chitin + H(2)O = chitosan + acetate.
      • Hydrolyzes the N-acetamido groups of N-acetyl-D-glucosamine residues in chitin.

      Acetylxylan esterase. [EC: 3.1.1.72]
      Deacetylation of xylans and xylo-oligosaccharides.
      • Catalyzes the hydrolysis of acetyl groups from polymeric xylan, acetylated xylose, acetylated glucose, alpha-napthyl acetate, p-nitrophenyl acetate but not from triacetylglycerol.
      • Does not act on acetylated mannan or pectin.
      		 6 A0A1Y3DZQ5 A0A2J9KK56 B3PIN1 B5ZA76 O25080 Q59674
      Endo-1,4-beta-xylanase. [EC: 3.2.1.8]
      Endohydrolysis of (1->4)-beta-D-xylosidic linkages in xylans.
        		 4 B3PIN1 P54865 P83513 Q59674
        Peptidoglycan-N-acetylglucosamine deacetylase. [EC: 3.5.1.104]
        Peptidoglycan-N-acetyl-D-glucosamine + H(2)O = peptidoglycan-D- glucosamine + acetate.
        • Modification of peptidoglycan by N-deacetylation is an important factor in virulence of Helicobacter pylori, Listeria monocytogenes and Streptococcus suis.
        • The enzyme from Streptococcus pneumoniae is a metalloenzyme using a His-His-Asp zinc-binding triad with a nearby aspartic acid and histidine acting as the catalytic base and acid, respectively.

        Gellan lyase. [EC: 4.2.2.25]
        Eliminative cleavage of beta-D-glucopyranosyl-(1->4)-beta-D- glucopyranosyluronate bonds of gellan backbone releasing tetrasaccharides containing a 4-deoxy-4,5-unsaturated D-glucopyranosyluronic acid at the non-reducing end. The tetrasaccharide produced from deacetylated gellan is beta-D-4-deoxy-Delta(4)-GlcAp-(1->4)-beta-D-Glcp-(1->4)-alpha-L-Rhap- (1->3)-beta-D-Glcp.
        • The enzyme is highly specific to gellan, especially deacetylated gellan.
