title: Participation of manganese ions complexed with tRNA in the interaction with amino acids and dipeptides.
abstract: Carboxyl groups of glycine, beta-alanine, gamma-aminobutyric acid and diglycine interact with Mn2+ coordinated by tRNA, as revealed by 1H and 13C NMR studies. The amino groups of these compounds interact with tRNA phosphate groups. The distances between the coordinated Mn2+ and carboxyl groups and the alpha-protons of glycine were determined. The role of Mn2+ and Mg2+ complexed with nucleic acids in the formation of specific complexes between proteins and nucleic acids is discussed.
