Effects of calcium on the gramicidin A single channel in phosphatidylserine membranes


In phosphatidylserine membranes the decrease in the conductance of the gramicidin A single channel caused by calcium is attributed to a reduction of surface potential and to a direct blocking of the pore (Apell et al. 1979). The aim of this paper is to make a, quantitative evaluation of these two effects. We recorded the conductance of gramicidin single… (More)
