Fig 5. Analysis of the substrate preferences of rhCPD using the tryptic peptide library.

Fig 5

(A) Substrate preferences of rhCPD at C-terminal (P1’) and (B) P1 positions. The number of times each amino acid was present in P1 or P1’ was determined for good substrates, weak substrates and non-substrates and represented. For P1 analysis, only substrates with permissive P1’ residues (Lys or Arg) were considered.
