Hydrolyzes chromogenic peptides at the carboxyl Arg or Lys, requires at least one more amino acid, preferably Arg, Phe, Val or Leu, between the terminal Arg or Lys and the amino-blocking group. The cysteine protease may play an important role in the development and differentiation of the parasites at several stages of their life cycle. Recombinant protein corresponding to aa123-467 from Trypanosoma cruzi Cruzipain, fused to 10X His-Tag at N-terminal and Myc-Tag at C-terminal, expressed in E. coli.
