Protein
Cruzipain
Gene
N/A
Organism
Trypanosoma cruzi
Status
Reviewed - Annotation score: 5 out of 5 - Experimental evidence at protein leveli

Functioni

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.

Catalytic activityi

Broad endopeptidase specificity similar to that of cathepsin L.

Enzyme regulationi

Strongly inhibited by E-64 (L-trans-epoxysuccinylleucylamido(4-guanidino)butane), Leupeptin, and N-alpha-p-tosyl-L-lysine chloromethyl ketone.
