ESR spectra of nitroxyl derivative labelling with parachlormercury benzoate bound with SH-groups of Ca, Mg-dependent ATPase in the presence of Mn2+ ions are studied. It has been concluded from the saturation curves of ESR spectra that Mn2+ is localized at the distance approximately 40 A from the SH-group of the enzyme active centre. Platinum compound (K2PtCl4) changes the spectrum of ESR 1 due to the displacement of the label from the enzyme SH-groups and disintegration of the sarcoplasmic reticulum structure. Palladium compound (Pd(NH3)4Cl2) produced no effect on the ESR 1 spectrum. |
