Representative DSC scans of WT Trx, pelB Trx and malE Trx.

<p>Scans were carried out in CGH-10 buffer (pH 7.4). The scan rate was 60°C /h and protein concentration was 0.2 mg/ml. Baseline subtracted excess heat capacity data as a function of temperature are shown. The data indicate that protein stability increases in the order malE Trx
