Figure 5.

Metastable equilibrium chemical activities of proteins. Logarithms of chemical activities of the proteins listed in Table 1 were calculated at 25°C and 1 bar using reactions written for (a) whole protein formulas or (b) residue equivalents of the proteins. Activities of the basis species were set to the values given in the Methods, and initial activities of the proteins were set to 10^-3. The vertical dashed lines represent the lower stability limit of H₂O.
