The affinity of SaBADH for ligands as studied by SPR. (a) Relative response and single binding isotherm fitting for NAD+ and NADH binding to the enzyme at pH 7.0 and 277 K. (b) Response and data fitting of the NADH–SaBADH interactions in the pH range 6.0–8.0 at 277 K. (c) Single binding isotherm fitting of the affinity of 3-dehydroquinic acid and NADH for SaBADH (green) and S. typhimurium LT2 3-dehydroquinate dehydratase (red) at 298 K and pH 7.0. (d) Affinity of immobilized SaBADH (green) and S. typhimurium LT2 3-dehydroquinate dehydratase (red) for the betaine aldehyde and betaine at 298 K and pH 7.0. |
