Fraction of surface Hnex exposed to solvent (rH) as a function of factor for surface area of amino acid residues (= f*t). Green dashed line, f*t = 0.6. (a) rH of MurD as a function of f*t (purple dotted line) (left axis). Pink dotted line, p value rH(p) of MurD (right axis). Pink shaded zone shows error of rH(p) of MurD. (b) rH of Hef-IDR as a function of f*t (blue dotted line) (left axis). Blue dotted line, rH(p) of Hef-IDR (right axis). Blue shaded zone shows error of rH(p) of Hef-IDR. This figure is prepared by the usage of IGOR Pro 6.34A (https://www.wavemetrics.com/forum/news-and-announcements/igor-634a-now-shipping) and Adobe Illustrator CC 2015.2.1 (19.2.1) (https://www.adobe.com/jp/products/illustrator.html).
