Experimental results on ion movement through gramicidin membrane channels are presented and discussed in terms of ion transport in the simplest single-file pore (for review see Urban, B.W. and Hladky, S.B. (1979) Biochim. Biophys. Acta 554, 410-429). Single-channel conductance and bi-ionic potential data for Na+, K+, Cs+, NH4+ and Tl+ are used to assign values to the rate constants of the model. Not all of the rate constants can be determined uniquely and simplifications are introduced to… CONTINUE READING
