Abstract: | We studied the effects of H2O/D2O substitution on the permeation and gating of the large conductance Ca2+-activated K+ channels in Chara gymnophylla droplet membrane using the patchclamp technique. The selectivity sequence of the channel was: K+>Rb+≫Li+, Na+, Cs+ and Cl-. The conductance of this channel in symmetric 100 mm KCl was found to be 130 pS. The single channel conductance was decreased... |
