Fig. 1.
Crystal contacts in the 1F1E8hu structure. (a) Both copies of the 1F1E8hu TcR are shown. The α chain is shown in light gray, and the β chain is shown in dark gray. Residues involved in crystal contacts within the crystallographic asymmetric unit (asu) are shown in red, and contacts between molecules in different asu's are depicted in green. (b) Overlay of the Cα domains of 1F1E8hu (dark gray) and JM22 (light gray), electron density at 1σ illustrating the shortened DE loop in 1F1E8hu, and residues 174–184 depicted in ball-and-stick. Carbons are highlighted in yellow, oxygens are highlighted in red, and nitrogens are highlighted in blue. Cartoons were produced using PyMOL (http://www.pymol.org).
