[[http://www.uniprot.org/uniprot/CYSP_TRYCR CYSP_TRYCR]] 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.
