FunFam 70: Alpha-glucan water dikinase 2

There are 1 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
Alpha-glucan, water dikinase. [EC: 2.7.9.4]
ATP + alpha-glucan + H(2)O = AMP + phospho-alpha-glucan + phosphate.
  • ATP appears to be the only phosphate donor.
  • No activity could be detected using GTP, UTP, phosphoenolpyruvate or diphosphate.
  • The protein phosphorylates glucans exclusively at O-6 of glucosyl residues.
  • The protein phosphorylates itself with the beta-phosphate of ATP, which is then transferred to the glucan.
