Crystal structure of cruzain bound to an alpha-ketoester

Template:ABSTRACT PUBMED 15727867

Function

[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.
