Arginine kinase of the flagellate protozoa Trypanosoma cruzi: Regulation of its expression and catalytic activity

In epimastigotes of Trypanosoma cruzi, the etiological agent of Chagas' disease, arginine kinase activity increased continuously during the exponential phase of growth. A correlation between growth rate, enzyme-specific activity and enzyme protein was observed. Arginine kinase-specific activity...
