2.7.9.4 amylopectin + ATP + H2O Arabidopsis thaliana essential step within starch metabolism. In Arabidopsis leaves starch turnover requires a close collaboration of alpha-glucan, water dikinase and phosphoglucan, water dikinase AMP + phospho-amylopectin + phosphate

2.7.9.5 ATP + [phospho-alpha-glucan] the enzyme phosphorylates granular starch that has previously been phosphorylated by EC 2.7.9.4, alpha-glucan, water dikinase Arabidopsis sp. AMP + O-phospho-[phospho-alpha-glucan] + phosphate
-
 ?
2.7.9.5 ATP + [phospho-alpha-glucan] the enzyme transfers the beta-phosphate of ATP to the phosphoglucan, whereas the gamma-phosphate is transferred to water. The protein phosphorylates itself with the beta-phosphate of ATP at a His residue of the enzyme, which is then transferred to the glucan Arabidopsis sp. AMP + O-phospho-[phospho-alpha-glucan] + phosphate
