The Influence of Hemolysins on the ATPase Activity and the Composition of the Erythrocyte Membrane

Abstract: Summary. The influence of low concentrations of some hemolysins on the erythrocyte membrane was investigated. Lysolecithin stimulates Mg^++ as well as Mg^++ + Na^+ + K^+ dependent ATPase in ghosts. Lecithin slightly stimulates ATPase only in saponin-treated ghosts. After saponin and digitonin treatment in concentrations enhancing the ATPase activity less phospholipids were eluted from ghosts than after water; saponin does not significantly change the level of free cholesterol, digitonin decreases it, while tha… Show more

“…Its function and role in the membrane has not yet been clarified, nor was its relation to Mg2+, Ca2+-dependent ATPase. It is to be found there in a latent form [11] and can be activated, for instance, by a certain disruption of the membrane [4,5,12]. Wins and Schoffeniels [14] found out that erythrocyte Mg2+, Ca2+-dependent ATPase can be influenced by substances interfering with the activity of flavoenzymes and suggest that ATPase activity can be controlled by the redox state of an electron carrier associated to it.…”
