| Comments |
"Increased selectivity requires an enhanced
intimacy of the channel's interaction with
the transported ions, an intimacy which in turn
would seem to imply hindered diffusion for all
ions. For example, Latorre et al. [primary source] established
that the EIM channel has a very high unitary conductance
(400 pS in 0.1 M KCl) and that the alkali
metal cations permeate "nonselectively," in proportion
to their free-solution mobilities." |
