Fig. 2From: Chaperone activity of serine protease HtrA of Helicobacter pylori as a crucial survival factor under stress conditionsInfluence of HtrAHpS221A (26695 strain) on the formation of large aggregates of denatured lysozyme. The graphs show the rates of formation of large lysozyme aggregates at 37 °C and pH 5.0 (a), 6.2 (b), 7.0 (c) and 8.0 (d). Samples without HtrA were used as a control. The molar ratio HtrA/lysozyme in the samples was 1:2. TCEP concentrations used: a 46 mM; b 40 mM; c 1.4 mM and d 0.05 mM. The error bars represent the standard deviation values from three independent measurementsBack to article page
