RESUMO
The maximal binding of 86Rb was noted when ions of Mg, ATP and Na were present simultaneously. The availability of olytoriside (1-10(-4)M), CaCl2 (1-10(-3)M) and phospholipase A (1-10(-5)M) in the medium and the removal of Na and substitution of ATP for ADP decreased to a different extent the binding of 86Rb.

RESUMO
On the strength of the study of tryptophan fluorescence of Na+, K+-ATPase preparation a conclusion about conformational changes of the enzume molecule at the level of its tertiary structure is made. The largest changes of intensity and position of fluorescence spectrum consequently the macromolecule structure are discovered at the formation of Mg-ATP-enzyme complex.
