Figure 4
Backbone trace of the thermolysin molecule with the 130 atoms with the greatest B-factor increases shown with spheres (corresponding to ∼5% of the atoms in the protein; oxygen = red, nitrogen = blue, carbon = wheat, sulfur = yellow, calcium = cyan). At 100 K (upper; two orthogonal views of the molecule are shown) the 130 greatest B-factor increases are distributed evenly throughout the molecule, and include the two methionine Sδ atoms (yellow). In contrast, at 160 K (lower) they are biased towards the surface, and include a surface-exposed calcium ion (cyan). Figure prepared using PYMOL.
