EC 2.7.9.4
starch-related R1 protein, GWD |
Description | Requires Mg2+. ATP appears to be the only phosphate donor. No activity could be detected using GTP, UTP, phosphoenolpyruvate or diphosphate. The protein phosphorylates glucans exclusively on O-6 of glucosyl residues. The protein phosphorylates itself with the β-phosphate of ATP, which is then transferred to the glucan. Reaction: ATP + α-glucan + H2O = AMP + phospho-α-glucan + phosphate |
