From: Bacterial chemotaxis towards polysaccharide pectin by pectin-binding protein
Binding assay between SPH1118 and pectin using DSF. (A) Fluorescence profile of SPH1118 in the absence (dotted line) and presence (solid line) of pectin at 5 µM. (B) The negative derivative curve plot obtained from the fluorescence profile (A). Relative minimal values of SPH1118 in the absence (dotted line) and presence (solid line) of pectin were determined as Tm values of 48.0 °C and 56.6 °C, respectively.
