ENZYME entry: EC 2.7.9.5

PURL: https://purl.expasy.org/enzyme/EC/2.7.9.5
Accepted Name
phosphoglucan, water dikinase
Reaction catalysed
[(1->4)-6-phospho-alpha-D-glucosyl](n) + n ATP + n H2O = [(1->4)-3,6-bisphospho-alpha-D-glucosyl](n) + n AMP + n phosphate + 2n H(+)
Comment(s)
  • The enzyme phosphorylates granular starch that has previously been phosphorylated by EC 2.7.9.4; 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 2.7.9.4, 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.
