Protein attributes

Sequence length	728 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is not processed.
Protein existence	Inferred from homology.

General annotation (Comments)

Function	Catalyzes the reversible transfer of the terminal phosphate of ATP to form a long-chain polyphosphate (polyP). HAMAP MF_00347
Catalytic activity	ATP + (phosphate)(n) = ADP + (phosphate)(n+1). HAMAP MF_00347
Post-translational modification	An intermediate of this reaction is the autophosphorylated ppk in which a phosphate is covalently linked to histidine residues through a N-P bond By similarity.
Sequence similarities	Belongs to the polyphosphate kinase family.
