CD spectroscopy and thermal stability measurements of WbgU. a Far UV (195–260 nm) spectra of WbgU at 20 °C (black line) and 37 °C (red line) indicating the folding status of the 4-epimerase in 20 mM sodium phosphate buffer at pH 7.75. CD data were reported as molar ellipticity (Θ). b Thermal unfolding profiles of WbgU (white squares), WbgU in the presence of either UDP-GlcNAc (blue squares) or UDP-GalNAc (yellow squares) were monitored at 220 nm
