Relaxometric determination of binding between Mn(II)–UDP and Mn(II)–UDP-glucose in aqueous solution Original Research Article

The applicability of relaxometry for the determination of formation constants of Mn(II)–UDP (log K = 3.78) and Mn(II)–UDP-glucose (log K = 2.98) complexes is demonstrated. The obtained value indicates a well-defined interaction between Mn(II) and UDP-glucose in aqueous solution (pH = 5.50) with ΔG = –4.07 kcal/mol.
