Mutarotase equilibrium exchange kinetics studied by 13C-NMR.

P W Kuchel1, B T Bulliman, B E Chapman.   

Abstract

The rates of exchange between the alpha- and beta-anomers of D-[1-13C]glucose, at equilibrium catalyzed by porcine kidney mutarotase (EC 5.1.3.3), were measured using 13C-NMR spin-transfer procedures. This entailed inversion-transfer and saturation-transfer experiments, and two-dimensional exchange spectroscopy (2D EXSY). The concentration and temperature dependences of the fluxes were studied; equilibrium exchange Michaelis constants, and the activation energy of the catalyzed reaction were thereby measured.
