ResumoX-ray evidence for the lysyl lateral amine group coordination to cupric ion is presented for the Cu(II) complex with L-lysyl-L-tyrosyl dipeptide. The dipeptide molecule is coordinated to the metal ion via all its functions. The α-amine, N− and COO- donors bind the metal ion forming two small chelate rings while ϵ-NH2 is coordinated to the other copper ion related by the screw axis and the polymeric complex is formed.
