Figure 1. Cleavage preferences of falcipain-2 and falcipain-3 against a tetrapeptide library.

P₁ P₂, P₃ and P₄ complete diverse libraries were used to determine specificities. Activities are displayed as percentage of the maximum for each position. Amino acids are represented by the single-letter code (n is for norleucine). Error bars represent standard deviations of results from three experiments.
