FunFam 53182: Maltodextrin glucosidase

There are 3 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
Alpha-glucosidase. [EC: 3.2.1.20]
Hydrolysis of terminal, non-reducing (1->4)-linked alpha-D-glucose residues with release of alpha-D-glucose.
  • Group of enzymes whose specificity is directed mainly toward the exohydrolysis of 1,4-alpha-glucosidic linkages, and that hydrolyze oligosaccharides rapidly, relative to polysaccharides, which are hydrolyzed relatively slowly, or not at all.
  • The intestinal enzyme also hydrolyzes polysaccharides, catalyzing the reactions of EC 3.2.1.3, and, more slowly, hydrolyzes 1,6-alpha-D- glucose links.

Neopullulanase. [EC: 3.2.1.135]
Hydrolysis of pullulan to panose (6-alpha-D-glucosylmaltose).
  • Cf. EC 3.2.1.41 and EC 3.2.1.57.

(74 more...)
Cyclomaltodextrinase. [EC: 3.2.1.54]
Cyclomaltodextrin + H(2)O = linear maltodextrin.
  • Also hydrolyzes linear maltodextrin.
  • Formerly EC 3.2.1.12 and EC 3.2.1.13.
