Figure 2.

The α carbon trace of Vα and Vβ regions of an H-2K^b-restricted, VSV peptide-specific TCR showing the position of residue 98 in the CDR3β loop. The TCR heterodimer was isolated from the VSV peptide-specific T cell clone N15 (15). CDR loops of the TCR α chain are labeled as α1, α2, and α3. CDR loops of the TCR β chain are labeled as β1, β2, and β3. Within CDR3β loop, the amino acid residue at position 98 is shown in light blue at the apex of the loop; other residues are shown in red. Figure is made with grasp (32).
