Figure 2. Inhibition of chymotrypsin-like activity of 20 S proteasome by PR-peptides.

Figure 2

The ability of PR11 and its mutants to inhibit the chymotrypsin-like activity of mammalian 20S proteasomes were assayed. Relative activities of the proteasome in the presence of various PR-peptides were assessed from the concentrations of the fluorescent methylcoumaramide (MCA) product.
