일반 설명

Molecular Weight: 71 kDa (homodimer consisting of two equal subunits of molecular weight 32-35 kDa)
Extinction Coefficient: E1% = 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.

애플리케이션

Inorganic pyrophosphatase (PPase) is a ubiquitous enzyme catalyzing the reaction PPi + H2O → 2Pi.
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.

Despite the increasing number of genes associated with Charcot-Marie-Tooth (CMT) disease, many patients currently still lack appropriate genetic diagnosis for this disease. Autosomal dominant mutations in aminoacyl-tRNA synthetases (ARSs) have been implicated in CMT. Here, we describe causal missense mutations
