title: [Sulfur ligands within the cluster formations of copper at its strong'binding sites on the cytoplasmic membrane of Escherichia coli].
abstract: The analysis of the saturation curves of ESR signals revealed a decrease in the relaxation rate of fast-relaxation Cu(I) complexes on the cytoplasmic membrane of E. coli after the interaction of these bacteria with low concentrations of SH-reagents. It was concluded that the observed changes are associated with the reorganization of Cu clusters due to the binding of SH groups incorporated into the clusters N-ethylmaleimide or Ag(I).
