A recombinant tyrosine aminotransferase from Trypanosoma cruzi has both tyrosine aminotransferase and alanine aminotransferase activities.
Tyrosine aminotransferase purified from epimastigotes of Trypanosoma cruzi displays an additional activity of alanine aminotransferase, absent in all other tyrosine aminotransferases characterized so far. Since the parasite's genome contains a high number of copies of the tyrosine aminotransferase gene, we could not rule out the possibility that two very similar proteins, with changed specifici...
متن کاملEnhancement of rat brain tyrosine aminotransferase activity by cortisol.
Administration of cortisol to rats enhanced brain tyrosine:2-oxoglutarate aminotransferase activity by a mechanism excluding stabilization, but possibly involving enhanced synthesis, of the enzyme.
متن کاملTyrosine Aminotransferase PURIFICATION AND CHARACTERIZATION
Tyrosine aminotransferase was highly purified from rat livers in which the enzyme had been induced by a glucocorticoid hormone. The preparation eluted from a DEAEcellulose column as a single peak gave a single precipitin line by the Ouchterlony double diffusion precipitin reaction and sedimented as a single boundary in the ultracentrifuge with an s20,W of 5.9. A molecular weight of 91,000 was d...
متن کاملPseudoisozymes of hepatic tyrosine aminotransferase.
Dexamethasone, insulin, and serum induce an additive increase in the activity of tyrosine aminotransferase (L-tyrosine : Z-oxoglutarate aminotransferase, EC 2.6.1.5) in hepatoma cells in tissue culture. By the criteria of immunotitration, heat stability, and electrophoresis on polyacrylamide gels, we have shown previously that all three effecters increase the cellular concentration of the same ...
متن کاملStructure of tyrosine aminotransferase from Leishmania infantum
The trypanosomatid parasite Leishmania infantum is the causative agent of visceral leishmaniasis (VL), which is usually fatal unless treated. VL has an incidence of 0.5 million cases every year and is an important opportunistic co-infection in HIV/AIDS. Tyrosine aminotransferase (TAT) has an important role in the metabolism of trypanosomatids, catalyzing the first step in the degradation pathwa...
