Figure 2. Stereoviews displaying (a) a Cα trace for SEC2 and (b) a comparison of Cα traces for SEC2 (black), SEB (red) and TSST-1 (green). The rms deviation between the Cα positions of 206 equivalent residues in SEC2 and SEB crystal structures is 0.94 å and the corresponding deviation between the Cα positions of 181 equivalent residues in SEC2 and TSST-1 crystal structures is 2.95 å. Structural alignments were performed using the Structure Homology Program (SHP) [64]. Figure 2.
