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

Cat. No.: HY-P71516
Handling Instructions Technical Support

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.

Description

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.

Background

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.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.

  • Dilution Calculator

  • Specific Activity Calculator

The reconstitution calculator equation

Volume (to add to vial) = Mass (in vial) ÷ Desired Reconstitution Concentration

Volume (to add to vial) = Mass (in vial) ÷ Desired Reconstitution Concentration
= ÷

The dilution calculator equation

Concentration (start) × Volume (start) = Concentration (final) × Volume (final)

This equation is commonly abbreviated as: C1V1 = C2V2

Concentration (start) × Volume (start) = Concentration (final) × Volume (final)
× = ×

The specific activity calculator equation

Specific Activity (Unit/mg) = 106 ÷ Biological Activity (ED50)

Specific Activity (Unit/mg) = 106 ÷ Biological Activity (ED50)
Unit/mg = 106 ÷ ng/mL
