Figure 3.

Relative metastabilities of proteins. log -pH diagrams at 25°C and 1 bar were constructed using activities of the basis species given in the Methods. Predominance field boundaries correspond to metastable equilibrium activities of proteins equal to 10^-3. The diagrams were made for (a) all of the proteins listed in Table 1 and (b) the proteins listed in Table 1 except for those appearing in the first diagram. The dashed line appearing in each diagram represents the lower (reducing) stability limit of H₂O.
