Dot plot of the differences between the Cα positions of each residue in the structures. To determine which regions of ChTg were most mobile in our data, we examined the five structures from the five intensity clusters and noted the distances among the Cα atoms for each of the 146 amino acids. We plotted the largest value for each amino acid. The data illustrate one extended region with very large variation (between residues 146 and 151, in the vicinity of the missing loop that is a normal cleavage point for α-chymotrypsin). There are also two shorter regions with smaller variation around Ser75 and Val200. |
