Exopolyphosphatase/PPX Protein, E.coli (His-SUMO)

Exopolyphosphatase/PPX proteins are dedicated to inorganic polyphosphate (polyP) degradation, expertly releasing orthophosphate from polyphosphate termini in a sustained manner. It shows a strong preference for long-chain polyphosphates, with moderate affinity for shorter sizes (approximately 15 residues). Exopolyphosphatase/PPX Protein, E.coli (His-SUMO) is the recombinant E. coli-derived Exopolyphosphatase/PPX protein, expressed by E. coli , with N-His, N-SUMO labeled tag. The total length of Exopolyphosphatase/PPX Protein, E.coli (His-SUMO) is 512 a.a., with molecular weight of ~74.0 kDa.

Exopolyphosphatase/PPX protein, specializing in the degradation of inorganic polyphosphates (polyP), proficiently releases orthophosphate in a processive manner from the termini of the polyP chain. Demonstrating a robust predilection for long-chain polyphosphates, this enzyme exhibits only modest affinity for smaller polyP sizes, typically around 15 residues. With its precision in catalyzing the breakdown of polyP, Exopolyphosphatase/PPX plays a crucial role in regulating phosphate metabolism and contributes to the dynamic balance of cellular phosphate pools.
