Figure 1.
Fig. 1. A representative part of the 2F[o]F[c] electron density map of SEA-Zn2+ in the core of the superantigen molecule. Observe the interactions between tyrosine residues that possibly contribute to the resistance^ of SEA to environmental factors such as high temperature or protease^ degradation. The 2F[o]F[c] electron density map is contoured at 1.2^ above the mean.
