For ion channels that possess multiple conductance states, it might be expected that ion selectivity would differ among states. Yet for many kinds of channels studied, the selectivity of subconductance states has been found to be similar to that of the main conductance state ( Hamill et al. 1981 ; Auerbach & Sachs, 1984 ; Fox, 1985 ; Bormann et .Kawano and colleagues show two distinct ion conductance states by embedding a single metal-organic porous molecule with Archimedean cuboctahedron geometry into a planar lipid bilayer.

Introduction. Two structural motifs of ion channels are found in nature, one based on transmembrane amphipathic α-helical peptides forming a hydrophilic pore (Unwin 2003), whereas the other one is characterized by β-barrels as is found in porines (Buchanan 1999).A wealth of information about ion channels has been gathered from the assembly of simple α .

ICReDD aims at acquiring an in-depth understanding of complex chemical reactions and to accelerate the efficient development of new chemical reactions.The acetylcholine-activated channel of vertebrate skeletal muscle, as manifested in cultured, developing cells, is able to adopt more than one conductance state. This paper briefly reviews the evidence for such multiple conductance channels and .Calculation of channel diameter from conductance The channel conductance was estimated from the slope of the I–V curve (n>3 at each voltage). The dependence of conductance on the salt concentration (n>3 at each concentration) was fitted to the Michaelis–Menten equation. g = g MAX / (1 + EC 50 /[KCl]) where g MAX is the maximum conductance.

Single-channel conductance can be seen directly in the amplitudes of current steps as the gates of channels open and close stochastically in an all-or-nothing manner in patch recording. (Fig. 1). The −1.5 pA (inward) unitary-current step sizes in that figure correspond to a single-channel conductance of ∼15 pS for those Na + channels. To the best of our knowledge, the idea of using MOPs to tune the ion conductance of a lipid membrane has not been considered so far. In a recent issue of Chem, Furukawa and colleagues 7 achieved this by designing a hybrid porous cuboctahedron consisting of an association of metal(II) dimers of octahedra (M = Rh or Cu) connected by dicarboxylate linkers .
