[Interaction of manganese II ions with proteins]

Electron and ESR-spectroscopic study was carried out of the interaction between manganese(II) ions with albumine and lysozome in water solutions at different manganese concentrations and ratios manganese/protein. The results obtained suggest presence of metal-protein interactions. At high manganese concentrations liotropic effect is observed. At high molecular ratios protein/manganese and manganese concentrations close to physiological ones formation of coordination compounds manganes(II) ions with proteins was observed.
