A new class EC 7, Translocases, has been added to the EC list. It will be part of ENZYME from release 2018_10. Read more about EC 7 here.

ENZYME entry: EC

Accepted Name
Phosphoglucan, water dikinase.
Reaction catalysed
ATP + (phospho-alpha-glucan) + H(2)O <=> AMP + O-phospho-(phospho-alpha-glucan) + phosphate
  • The enzyme phosphorylates granular starch that has previously been phosphorylated by EC; there is no activity with unphosphorylated glucans.
  • It transfers the beta-phosphate of ATP to the phosphoglucan, whereas the gamma-phosphate is transferred to water.
  • In contrast to EC, which phosphorylates the glucose groups in glucans predominantly on O-6, this enzyme phosphorylates glucose groups in phosphorylated starch predominantly on O-3.
  • The protein phosphorylates itself with the beta-phosphate of ATP, which is then transferred to the glucan.
