What is it about?

T. cruzi shares a unique antioxidant defence system. Tryparedoxin peroxidase has been identified as a constituent of the complex peroxidase system in the trypanosomatid Crithidia fasciculata . In trypanosomatids, hydroperoxides are reduced at the expense of NADPH by means of a cascade of three oxidoreductases: the flavoprotein trypanothione reductase, tryparedoxin and tryparedoxin peroxidase. Inhibitors of these enzymes are presumed to be trypanocidal drugs.
