Figure 5From: The 3.5 ångström X−ray structure of the human connexin26 gap junction channel is unlikely that of a fully open channelComparison of PMFs for the permeation of charged (black) and uncharged calcein (red). The main graphs show PMF profiles for a hCx26wt hemichannel. Inset: corresponding free energy profiles, W(z), for a complete gap junction channel obtained by reflecting the hemichannel PMFs about a vertical axis through the z H abscissa.Back to article page
