Figure 1. Crystal structures of H-2K^b in complex with gp34 and NY-gp34.

Overall schematic views of the H-2K^b/gp34 and H-2K^b/NY-gp34 MHC complexes are presented in the left part of panels A and B. The α1, α2 and α3 domains of the MHC heavy chain are colored in white. The β₂m subunit is colored in green. The peptides are in blue. The 2F_o-F_c electron density maps for the peptides gp34 and NY-gp34 when bound to H-2K^b presented in the right part of panels A and B, respectively, are contoured at 1.0 σ. The final models are displayed for comparison. The peptides, depicted with their N-termini to the left and their C-termini to the right, are displayed ‘from above’ as seen by the TCRs.
