Figure 6.
(a–c) Structural rearrangements in CDR2 , CDR3 and CDR3 induced by binding to mutant TPI–DR1. Bound E8, green; unbound E8, magenta; HLA-DR1, gold; mutant TPI, gray. Residues from E8 and DR1 involved in interactions with peptide are identified. (d) Superposition of mutant TPI–DR1 in a form without bound ligand (peptide, cyan; MHC, violet) and in complex with E8 (peptide, gray; MHC, gold). Arrow indicates residues 55–59 of the HLA-DR1 1 domain. (e) Conformational changes in TPI residues that contact E8. Residues of TPI involved in interactions with E8 are identified. Residue designations as in Figure 4.
