The SASA of residue B24 (the upper panel of Figure ), on the other hand, had a higher correlation with the proteolytic stability of the structure. Specifically, GF 13 and GF 10, the two most proteolytically stable glycoforms, had significantly lower SASA value at residue B24. As for the glycoforms that had a lower SASA value at this site, except for GF 7, all had comparable proteolytic stability to the wild type. This higher correlation can also be seen from the magnitude of the corresponding Kendall's tau correlation coefficient, which was higher than those of Metric 1.
