|Title:||NMR Investigation of the Copper(II)-Carnosine Complex in Water Solution||Authors:||Gaggelli, Elena
|Keywords:||Copper(II) complexes; peptide molecules||Issue Date:||1988||Project:||None||Journal:||JOURNAL OF INORGANIC BIOCHEMISTRY||Abstract:||
The predominant species in water solution of excess carnosine and Cu2+ ions was characterized by measuring 13C and 1H spin-lattice and spin-spin relaxation rates. Four peptide molecules were calculated to be coordinated to the metal through the imidazole nitrogen. Evaluation of ion-proton distances demonstrated that metal complexation does not involve severe changes in conformation of the peptide.
