Comments [?]

Function Bifunctional serine/threonine kinase and phosphorylase involved in the regulation of the phosphoenolpyruvate synthase (PEPS) by catalyzing its phosphorylation/dephosphorylation.
Catalytic activity RHEA:46020: [pyruvate, water dikinase] + ADP = [pyruvate, water dikinase]-phosphate + AMP + H(+)
EC 2.7.11.33
RHEA:48580: [pyruvate, water dikinase]-phosphate + H(+) + phosphate = [pyruvate, water dikinase] + diphosphate
EC 2.7.4.28
Similarity Belongs to the pyruvate, phosphate/water dikinase regulatory protein family. PSRP subfamily.
