Protein
Exopolyphosphatase
Gene
ppx, VC_0722
Organism
Vibrio cholerae serotype O1 (strain ATCC 39315 / El Tor Inaba N16961)
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 By similarity.

Catalytic activityi

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

Cofactori

Magnesium By similarity.
