ENZYME entry: EC 2.7.9.4
| Accepted Name |
|---|
| Alpha-glucan, water dikinase.
|
| Alternative Name(s) |
|---|
| Alpha-glucan,water dikinase. |
| Starch-related R1 protein. |
| Reaction catalysed |
|---|
| ATP + alpha-glucan + H(2)O <=> AMP + phospho-alpha-glucan + phosphate |
| Cofactor(s) |
|---|
| Magnesium.
|
| Comment(s) |
|---|
- 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.
