Protein

Exopolyphosphatase

Gene

ppx

Organism
Escherichia coli O6:H1 (strain CFT073 / ATCC 700928 / UPEC)
Status
Reviewed - Annotation score: 2 out of 5- Protein inferred from homologyi

Functioni

Degradation of inorganic polyphosphates. Orthophosphate is released progressively from the ends of polyphosphate of circa 500 residues long, while chains of circa 15 residues compete poorly with polyphosphate as substrate (By similarity).By similarity

Catalytic activityi

(Polyphosphate)(n) + H2O = (polyphosphate)(n-1) + phosphate.
