Figure 4. Relationship of peptide with the TPR clusters. a, View of the interaction of TPRs 1 -3 (yellow) with the peptide ligand (ball-and-stick, in red). b, View of the interaction of TPRs 5 -7 (cyan) with the peptide ligand. c, Molecular surface representation of TPRs 1 -3 interacting with the peptide ligand (yellow). Blue represents regions of positive potential and red represents regions of negative potential, at the 10 kT e^-1 level. d, Similar representation as in (c), showing TPRs 5 -7 with peptide. (c,d) were generated using GRASP35.
