Presence and subcellular localization of tyrosine aminotransferase and p-hydroxyphenyllactate dehydrogenase in epimastigotes of Trypanosoma cruzi

Cell-free extracts of epimastigotes of Trypanosoma cruzi contain tyrosine aminotransferase (TAT) and p-hydroxyphenyllactate dehydrogenase (pHPLDH). The TAT activity could be separated from aspartate aminotransferase (ASAT) by polyacrylamide gel electrophoresis or DEAE-cellulose chromatography; the l...
