  • Inorganic pyrophosphatase (PPase) catalyzes the hydrolysis of inorganic pyrophosphate to form orthophosphate
  • Enhances yields of RNA in transcription reactions
  • Isolated from a recombinant source
Inorganic pyrophosphatase (PPase) catalyzes the hydrolysis of inorganic pyrophosphate to form orthophosphate.

A variety of metabolic reactions generate inorganic pyrophosphate as a reaction byproduct. Such reactions are rendered irreversible when the pyrophosphate is degraded by pyrophosphatase (1). RNA and DNA synthesis are examples of reactions that can be pulled far in the synthesis direction by the action of inorganic pyrophosphatase.
Highlights
  • Isolated from a recombinant source.
Product Source
PPase is prepared from an E. coli strain containing a genetic fusion of the Saccharomyces cerevisiae ppa gene and the gene coding for Mycobacterium xenopi GyrA intein. The final product has been cleaved and purified from the intein fusion partner. Developed by the Biohelix Corporation, and produced at New England Biolabs.

Properties & Usage

Unit Definition

One unit is the amount of enzyme that will generate 1 µmol of phosphate per minute from inorganic pyrophosphate under standard reaction conditions (a 10 minute reaction at 25°C in 100 mM Tris-HCl, [pH 7.2], 2 mM MgCl2 and 2 mM PPi in a reaction volume of 0.5 ml).

Storage Buffer

20 mM Tris-HCl
100 mM KCl
1 mM DTT
0.1 mM EDTA
50% Glycerol
pH 8 @ 25°C

Molecular Weight

Theoretical: 71 kDa


Notes
  • While a specific NEBuffer is not supplied, Yeast Inorganic Pyrophosphatase works well in any buffer containing Mg++ (1-10 mM). This enzyme is typically used in RNA IVT reactions, where the Mg++ concentration falls within this range.
