Figure 4.
Fig. 4. Differential scanning calorimetry data for the
unfolding of wild-type arginase (solid line), R308A (dashed and
dotted line), R308E (dotted line), and R308K (dashed line) shown
as excess molar heat capacity versus temperature. All scans are
normalized per mole of arginase subunit. Conditions were as
follows: 20 mM NaPO[4], 150 mM NaCl, 0.1 mM MnCl[2], pH 7.4, and
0.4 mg/ml arginase.
