FunFam 31: Glycogen debranching enzyme

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
Limit dextrin alpha-1,6-maltotetraose-hydrolase. [EC: 3.2.1.196]
Hydrolysis of (1->6)-alpha-D-glucosidic linkages to branches with degrees of polymerization of three or four glucose residues in limit dextrin.
  • This bacterial enzyme catalyzes a reaction similar to EC 3.2.1.33.
  • However, while EC 3.2.1.33 removes single glucose residues linked by 1,6-alpha-linkage, and thus requires the additional activity of EC 2.4.1.25 to act on limit dextrins formed by EC 2.4.1.1, this enzyme removes maltotriose and maltotetraose chains that are attached by 1,6-alpha-linkage to the limit dextrin main chain, generating a debranched limit dextrin without a need for another enzyme.
