    • When the density of negatively charged membrane lipids increases, the ion conductance of some bilayer-incorporated ion channels including gramicidin A and porin increases as well due to a higher concentration of positive ions near the channel mouth and thus a higher probability for an ion to enter the channel; see discussion in refs 21 and 27.

    • note
    • 34 It was suggested that salt ions can screen the pore charges diminishing the translocation rates (although the "ion blockage" mechanism cannot be completely excluded as well) indicating a possible 2-fold role of salt in solution on the conductivity of these channels.
