Figure 1.

Experimental data (black dots) for Phy (upper) and dgPhy (lower) plotted against model fits (gray lines), where light gray, gray, and dark gray lines represent solutions of 0.0 M, 0.3 M, and 1.0 M NaCl. The Phy protein concentrations were ∼86 mg/ml (left) and ∼153 mg/ml (right) and the dgPhy concentrations were ∼52 mg/ml (left) and ∼80 mg/ml (right). For the purpose of improving the visibility, the 0.3-M and 1.0-M data sets were multiplied by factors of 2 and 4, respectively.
