Effect of HtrAEcS210A and HtrAHpS221A on aggregation of lysozyme at various temperature and pH. The assays were performed in a spectrofluorimeter in thermostated cuvette holders at temperature and pH values indicated in each panel. Samples without HtrA were used as a control. The samples were prepared and analysed as described in Materials and methods. The TCEP concentration used in the assays were: 37 °C (a) pH 5.0- 15 mM (c) pH 6.2–0.35 mM (e) pH 7.0–0.1 mM (g) pH 8.0–0.03 mM; 42 °C (b) pH 5.0–3.5 mM (d) pH 6.2–0.4 mM (f) pH 7.0–0.025 mM (h) pH 8.0–0.02 mM
