Abstract

The effect of androgens (testosterone, androsterone, dehydroepiandrosterone and dehydroepiandrosterone sulfate) on erythrocyte membrane during their nonspecific binding was investigated. The change in erythrocyte membrane Na+,K+-ATPase activity was measured at different hormone concentration in a suspension. It is shown that the dependence has dome-shaped character: at the elevated hormone concentration Na+,K+-ATPase activity starts to increase, reaches its maximum, and then decreases. The hypothesis is put forward that an increase in microscopists of erythrocyte membrane first intensifies Na+,K+-ATPase activity due to the growth of the maximum energy of membrane phonons, and then decreases it due to hindering conformational transitions in the enzyme molecule.
