Description:
The Pyrophosphatase, Inorganic (PPase) catalyzes the hydrolysis of inorganic pyrophosphate to two orthophosphates. The enzyme requires a divalent metal cation, with Mg2+ conferring the highest activity.

Application:
- High yield synthesis of RNA by in vitro transcription(1,2)
- DNA polymerization reactions: preventing accumulation of pyrophosphate(3, 4)
- Removal of contaminant PPi in reagents used for SNP genotyping by methods based on the detection of pyrophosphate(5)

Source:
E. coli cells with a cloned ppa gene of Sacharomyces cerevisiae.

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 Conditions:
20 mM Tris-HCL
100 mM KCl
1 mM Dithiothreitol
0.1 mM EDTA
50% Glycerol
pH 8.0 @ 25°C

Recommended Storage Conditions: -20°C
