Structure of triosephosphate isomerase from Cryptosporidium parvum
Cryptosporidium parvum is one of several Cryptosporidium spp. that cause the parasitic infection cryptosporidiosis. Cryptosporidiosis is a diarrheal infection that is spread via the fecal-oral route and is commonly caused by contaminated drinking water. Triosephosphate isomerase is an enzyme that is ubiquitous to all organisms that perform glycolysis. Triosephosphate isomerase catalyzes the for...
متن کاملOrganic solutes in hyperthermophilic archaea.
We examined the accumulation of organic solutes under optimum growth conditions in 12 species of thermophilic and hyperthermophilic Archaea belonging to the Crenarchaeota and Euryarchaeota. Pyrobaculum aerophilum, Thermoproteus tenax, Thermoplasma acidophilum, and members of the order Sulfolobales accumulated trehalose. Pyrococcus furiosus accumulated di-myo-inositol-1,1(prm1)(3,3(prm1))-phosph...
متن کاملThe mechanism of the triosephosphate isomerase reaction.
The interconversion of dihydroxyacetone phosphate and glyceraldehyde 3-phosphate catalyzed by the enzyme triosephosphate isomerase was first demonstrated by Meyerhof and Kiessling (1). Since then studies with the enzyme have disclosed little about the mechanism of this reaction. Such an interconversion may be envisioned as occurring by formation of an enediol as, based on chemical analogy (2)) ...
متن کاملCrystal structure of triosephosphate isomerase from Trypanosoma cruzi in hexane.
To gain insight into the mechanisms of enzyme catalysis in organic solvents, the x-ray structure of some monomeric enzymes in organic solvents was determined. However, it remained to be explored whether the structure of oligomeric proteins is also amenable to such analysis. The field acquired new perspectives when it was proposed that the x-ray structure of enzymes in nonaqueous media could rev...
متن کاملTriosephosphate isomerase deficiency: a neurodegenerative misfolding disease.
A number of neurodegenerative diseases are mediated by mutation-induced protein misfolding. The resulting genetic defects, however, are expressed in varying phenotypes. Of the several well-established glycolytic enzyme deficiencies, triosephosphate isomerase (TPI) deficiency is the only one in which haemolytic anaemia is coupled with progressive, severe neurological disorder. In a Hungarian fam...
