KEGG   ENZYME: 2.7.9.4
Entry
EC 2.7.9.4                  Enzyme                                 
Name
alpha-glucan, water dikinase;
starch-related R1 protein;
GWD
Class
Transferases;
Transferring phosphorus-containing groups;
Phosphotransferases with paired acceptors
Sysname
ATP:alpha-glucan, water phosphotransferase
Reaction(IUBMB)
ATP + alpha-glucan + H2O = AMP + phospho-alpha-glucan + phosphate
Substrate
ATP [CPD:C00002];
alpha-glucan [CPD:C00912];
H2O [CPD:C00001]
Product
AMP [CPD:C00020];
phospho-alpha-glucan;
phosphate [CPD:C00009]
Comment
Requires Mg2+. ATP appears to be the only phosphate donor. No activity could be detected using GTP, UTP, phosphoenolpyruvate or diphosphate [1]. The protein phosphorylates glucans exclusively on O-6 of glucosyl residues [2]. The protein phosphorylates itself with the beta-phosphate of ATP, which is then transferred to the glucan [1].
History
EC 2.7.9.4 created 2002
