|Phosphoglucan, water dikinase.
|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 184.108.40.206; there is no activity with
- It transfers the beta-phosphate of ATP to the phosphoglucan, whereas
the gamma-phosphate is transferred to water.
- In contrast to EC 220.127.116.11, 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.
