Figure 4. (a) Hydrophobic residues in the propeptide interacting with subtilisin BPN′ represented by the space-filling model. Residues drawn in magenta (propeptide) and green (subtilisin BPN′) are intermolecularly contacting with each other (based on 1SPB in PDB). (b) Corresponding amino acid residues in POW (magenta). Note that Gly40 is missing since it has no side-chain.
