Primary structure of human triosephosphate isomerase.
Human placental triosephosphate isomerase was isolated by an improved procedure and recovered with the highest specific activity ever reported. Employing this purification procedure, sufficient amounts of the enzyme were obtained for detailed primary structural studies. For sequences analysis, the enzyme was reduced and carboxymethylated and subjected to tryptic and chymotryptic digestions. The...
متن کاملStructure 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 کاملCrystal structure of recombinant human triosephosphate isomerase at 2.8 A resolution. Triosephosphate isomerase-related human genetic disorders and comparison with the trypanosomal enzyme.
The crystal structure of recombinant human triosephosphate isomerase (hTIM) has been determined complexed with the transition-state analogue 2-phosphoglycolate at a resolution of 2.8 A. After refinement, the R-factor is 16.7% with good geometry. The asymmetric unit contains 1 complete dimer of 53,000 Da, with only 1 of the subunits binding the inhibitor. The so-called flexible loop, comprising ...
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 کاملDrosophila model of human inherited triosephosphate isomerase deficiency glycolytic enzymopathy.
Heritable mutations, known as inborn errors of metabolism, cause numerous devastating human diseases, typically as a result of a deficiency in essential metabolic products or the accumulation of toxic intermediates. We have isolated a missense mutation in the Drosophila sugarkill (sgk) gene that causes phenotypes analogous to symptoms of triosephosphate isomerase (TPI) deficiency, a human famil...
