Figure 2From: Orthophosphate binding at the dimer interface of Corynebacterium callunae starch phosphorylase: mutational analysis of its role for activity and stability of the enzymeInactivation of R141A and S174A at 45°C. A 50 mM triethanolamine buffer, pH 7.0, was used. The protein concentration was 35 μg/ml (A) and 20 μg/ml (B). Symbols show the experimental data and solid lines are the corresponding straight-line fits. Representative data are shown. Conditions: no Pi added (full circles); 10 mM Pi (open circles).Back to article page
