Descrizione generale
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.

Improved therapies for the treatment of Trypanosoma brucei, the etiological agent of the neglected tropical disease human African trypanosomiasis, are urgently needed. We targeted T. brucei methionyl-tRNA synthetase (MetRS), an aminoacyl-tRNA synthase (aaRS), which is considered an important drug target

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

Grain chalkiness is a highly undesirable quality trait in the marketing and consumption of rice grain. However, the molecular basis of this trait is poorly understood. Here we show that a major quantitative trait locus (QTL), Chalk5, influences grain chalkiness
