ENZYME entry: EC 3.2.1.196

Accepted Name
Limit dextrin alpha-1,6-maltotetraose-hydrolase.
Alternative Name(s)
Glycogen debranching enzyme.
Reaction catalysed
Hydrolysis of (1->6)-alpha-D-glucosidic linkages to branches with degrees of polymerization of three or four glucose residues in limit dextrin
Comment(s)
  • 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.
