KEGG   ENZYME: 2.7.9.5
Entry
EC 2.7.9.5                  Enzyme                                 
Name
phosphoglucan, water dikinase;
PWD;
OK1
Class
Transferases;
Transferring phosphorus-containing groups;
Phosphotransferases with paired acceptors
Sysname
ATP:phospho-alpha-glucan, water phosphotransferase
Reaction(IUBMB)
ATP + [phospho-alpha-glucan] + H2O = AMP + O-phospho-[phospho-alpha-glucan] + phosphate
Substrate
ATP [CPD:C00002];
[phospho-alpha-glucan];
H2O [CPD:C00001]
Product
AMP [CPD:C00020];
O-phospho-[phospho-alpha-glucan];
phosphate [CPD:C00009]
Comment
The enzyme phosphorylates granular starch that has previously been phosphorylated by EC 2.7.9.4, alpha-glucan, water dikinase; there is no activity with unphosphorylated glucans. It transfers the beta-phosphate of ATP to the phosphoglucan, whereas the gamma-phosphate is transferred to water [1]. In contrast to EC 2.7.9.4, which phosphorylates glucose groups in glucans on O-6, this enzyme phosphorylates glucose groups in phosphorylated starch on O-3 [2]. The protein phosphorylates itself with the beta-phosphate of ATP, which is then transferred to the glucan [1].
History
EC 2.7.9.5 created 2005
