Figure 3. The net cleavage specificity of BCP and HP proteases for the degradome-wide substrates.

The cleavage positions P and P′ defined by Schechter I. and Berger A. (Papain Biochem Biophys Res Commun 1967, 27: 157–162) are adopted herein to present the specificity measured from ∼1000 peptidome peptides listed in Table S2.
