title: Coordination of Gly-Tyr x Pd(II) complex to GMP nucleotide.
abstract: Coordination of the glycyl-L-tyrosinate x Pd(II) complex to guanosine-5'-monophosphate (GMP) has been studied using 1H, 13CV NMR and electron spectra methods. Two kinds of monomeric ternary complexes were found in aqueous solutions: Gly-Tyr x Pd(II)-N7(GMP) complex (Pd-N7) at pH range 3 - 9 and Gly-Tyr x Pd(II)--N1(GMP) complex (Pd-N1) at pH above 5.2. The influence of the aromatic ring of tyrosine upon the chemical shifts for the -N7 bonded nucleotide molecule suggest that the plane of the purine ring and that of the Gly-Tyr x Pd(II) complex are almost perpendicular to each other.
