Figure 13From: Peptide binding to HLA-DP proteins at pH 5.0 and pH 7.0: a quantitative molecular docking studyPeptide binding pocket 9. The α chain residues are shown in light blue, the β chain residues – in darksalmon. The trimorphic Ala/Asp/Glu55β is shown in green. Asn69α and Thr72α (given in magenta) make H-bonds with p9 residue Ser (given as SER-11 in orange).Back to article page
