The surface potential drawings around the Hdj1 and Sis1 peptide-binding sites determined by Swiss-PDBviewer. Blue and red denote positively and negatively charged regions, respectively. a) Surface potential drawing presentation of the Hdj1 peptide-binding site. The residues of Hdj1 involved in forming the peptide-binding site are labeled in black. The Lysine residues involved in binding the Hsp70 C-terminal EEVD motifs are labeled in white. b) Surface potential drawing presentation of the Sis1 peptide-binding site.
