FunFam 82143: Glucose-1-phosphate adenylyltransferase

There are 2 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.

    Glycogen phosphorylase. [EC: 2.4.1.1]
    ((1->4)-alpha-D-glucosyl)(n) + phosphate = ((1->4)-alpha-D-glucosyl)(n-1) + alpha-D-glucose 1-phosphate.
    • This entry covers several enzymes from different sources that act in vivo on different forms of (1->4)-alpha-D-glucans.
    • Some of these enzymes catalyze the first step in the degradation of large branched glycan polymers - the phosphorolytic cleavage of alpha-1,4-glucosidic bonds from the non-reducing ends of linear poly(1->4)-alpha-D-glucosyl chains within the polymers.
    • The enzyme stops when it reaches the fourth residue away from an alpha-1,6 branching point, leaving a highly branched core known as a limit dextrin.
    • The description (accepted name) of the enzyme should be modified for each specific instance by substituting 'glycogen' with the name of the natural substrate, e.g. maltodextrin phosphorylase, starch phosphorylase, etc.
