Özet
Structures corresponding to energy minima and the binding of cadmium cation to threonine (Thr) in model systems [Cd(Thr) n]2+ (n = 1-3) were studied theoretically. Quantum chemical computations were performed within the framework of the density functional theory using the B3LYP, BLYP, and P functionals. In the optimized structures of the complexes [CdThr] 2+ and [Cd(Thr)2]2+, threonine acts as a bidentate ligand and cadmium binds to oxygen atoms of carbonyl and hydroxyl groups with the formation of one and two six-mem- bered rings, respectively. In the complex [Cd(Thr)3]2+, cadmium binds to three nitrogen atoms and three oxygen atoms of carbonyl groups in three Thr molecules to form three five-mem- bered rings. © 2010 Springer Science+Business Media, Inc.
