Artykuł
A new vasopressin analogue, [His1,6]AVP, was synthesized and characterized by potentiometric measurements as well as by UV-Vis, CD and EPR spectroscopy. At the physiological pH the peptide forms a stable complex with Cu2+ ions which is characterized by the {NH2, NIm, NIm(macrochelate)} binding mode. The replacement of both Cys by His residues in the vasopressin sequence results in a very significant increase in the efficiency of Cu2+ binding.
