Abstract

The pentose phosphate pathway has been studied in Trypanosoma cruzi, Clone CL Brener. Functioning of the pathway was demonstrated in epimastigotes by measuring the evolution of (14)CO(2) from [1-(14)C] or [6-(14)C]D-glucose. Glucose consumption through the PPP increased from 9.9% to 20.4% in the presence of methylene blue, which mimics oxidative stress. All the enzymes of the PPP are present in the four major developmental stages of the parasite. Subcellular localisation experiments suggested that the PPP enzymes have a cytosolic component, predominant in most cases, although all of them also seem to have organellar localisation(s).
