Fig. 5. a: Near-UV CD ellipticity of GDH (2.75 mg/ml) at 280 nm ([q]280) vs. various concentrations of octyl glucoside between 0-20 mM in 50 mM sodium phosphate buffer, pH 7.6. b: Decrease in the near-UV CD ellipticity ([q]280) of GDH (2.75 mg/ml) with increasing concentrations of octyl glucoside (0-20 mM). The figure emphasizes the disappearance of some tertiary structure of GDH due to octyl glucoside binding.
