FIG. 2. Dimerization of SpeJ. Stereo view of the SPE-J
dimer, with the two molecules shown in blue and yellow. Side
chains that make significant contributions to the dimer
interface are shown in red, with the major contributors labeled:
Y, Tyr-14; I, Ile-19; F, Phe-77; and R, Arg-181. The C-terminal
domain in each monomer provides the binding site for the zinc
ion (gray sphere) that binds to MHC-II. Fig. drawn with
MOLSCRIPT (43) and rendered with RASTER3D (44).
