Extinction Coefficient: E^1% = 14.5 (280 nm)
pI: 4.75
This ubiquitous enzyme serves to drive metabolic reactions that produce pyrophosphate, since these reactions typically have equilibrium constants near unity. The catalytic mechanism has been described in the literature. Inorganic pyrophosphatase is a metalloprotease that requires Mg²⁺ for maximal activity. Although the hydrolysis of inorganic pyrophosphate is specific in the presence of Mg²⁺, both ADP and ATP can be hydrolyzed if zinc is present.

Aplicación

Inorganic pyrophosphatase (PPase) is a ubiquitous enzyme catalyzing the reaction PP_i + H₂O → 2P_i.
It plays an important role in protein, RNA, and DNA synthesis.

Pyrophosphatase has been used:

• as a component of the reaction buffer used in aminoacylation assay to quantify incorporation of [3H]L-methionine into tRNA.
• as a component of PCR mixture.
