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
Exopolyphosphatase. [EC: 3.6.1.11]

    Guanosine-5'-triphosphate,3'-diphosphate diphosphatase. [EC: 3.6.1.40]
    Guanosine 5'-triphosphate,3'-diphosphate + H(2)O = guanosine 3',5'-bis(diphosphate) + phosphate.
    • Also hydrolyzes other guanosine 5'-triphosphate derivatives with at least one unsubstituted phosphate group on the 3'-position, but not GTP, ATP or adenosine 5'-triphosphate,3'-diphosphate.
