La. Volodina et al., Sulfur ligands included in Cu-clusters at sites of strong binding of Cu bythe cytoplasmic membrane of Escherichia coli, BIOFIZIKA, 44(1), 1999, pp. 59-65
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 concen
trations of SH-reagents. It was concluded that the observed changes are ass
ociated with the reorganization of Cu clusters due to the binding of SH gro
ups icorporated into the clusters N-ethylmaleimide or Ag(I).
