FunFam 11548: Glycogen operon protein GlgX homolog

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
Glucose-1-phosphate adenylyltransferase. [EC: 2.7.7.27]
ATP + alpha-D-glucose 1-phosphate = diphosphate + ADP-glucose.
    3 A0A0E1SQJ4 A0A0H3PEU7 A4N0C7
    1,4-alpha-glucan branching enzyme. [EC: 2.4.1.18]
    Transfers a segment of a (1->4)-alpha-D-glucan chain to a primary hydroxy group in a similar glucan chain.
    • Converts amylose into amylopectin.
    • The description (official name) requires a qualification depending on the product, glycogen or amylopectin, e.g. glycogen branching enzyme, amylopectin branching enzyme.
    • The latter has frequently been termed Q-enzyme.
    2 A4NYI0 A5UEJ3
    Pullulanase. [EC: 3.2.1.41]
    Hydrolysis of (1->6)-alpha-D-glucosidic linkages in pullulan, amylopectin and glycogen, and in the alpha- and beta-limit dextrins of amylopectin and glycogen.
    • Different from EC 3.2.1.142 in its action on glycogen, and its rate of hydrolysis of limit dextrins.
    • Its action on amylopectin is complete.
    • Maltose is the smallest sugar that it can release from an alpha- (1->6)-linkage.
    • Formerly EC 3.2.1.69.
