FunFam 9603: Isomaltotrio-dextranase precusor

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
Dextranase. [EC: 3.2.1.11]
Endohydrolysis of (1->6)-alpha-D-glucosidic linkages in dextran.
    4 A0A089Z938 P39652 P70744 P77813
    Dextran 1,6-alpha-isomaltotriosidase. [EC: 3.2.1.95]
    Hydrolysis of (1->6)-alpha-D-glucosidic linkages in dextrans, to remove successive isomaltotriose units from the non-reducing ends of the chains.
      1 Q9WXI3
      Isopullulanase. [EC: 3.2.1.57]
      Hydrolysis of pullulan to isopanose (6-alpha-maltosylglucose).
      • The enzyme has practically no action on starch.
      • Panose (4-alpha-isomaltosylglucose) is hydrolyzed to isomaltose and glucose.
      • Cf. EC 3.2.1.41 and EC 3.2.1.135.
