Protein attributes

Sequence length	277 AA.
Sequence status	Complete.
Protein existence	Evidence at protein level

General annotation (Comments)

Function	Bifunctional serine/threonine kinase and phosphorylase involved in the regulation of the phosphoenolpyruvate synthase (PEPS) by catalyzing its phosphorylation/dephosphorylation. Ref.7
Catalytic activity	ADP + [Pyruvate, water dikinase] = AMP + [pyruvate, water dikinase] phosphate. Ref.7 [Pyruvate, water dikinase] phosphate + phosphate = [pyruvate, water dikinase] + diphosphate. Ref.7
Subunit structure	Homotetramer. Ref.7
Sequence similarities	Belongs to the pyruvate, phosphate/water dikinase regulatory protein family. PSRP subfamily.
Sequence caution	The sequence M69116 differs from that shown. Reason: Frameshift at positions 64 and 90.
