Figure 4: Comparison of ion-conducting pores.

Figure 4:

The shape and size of the ion-conducting pore of (a) EDTA-drTRPM2, (b) ADPR/Ca2+-drTRPM2, (c) Ca2+-nvTRPM2, (d) Ca2+/DVT-hsTRPM4, and (e) mmTRPM7 (not full length). The side chains of restriction residues are shown as sticks. Purple, green, and red spheres define pore radii of > 2.3 Å, 1.2–2.3 Å, and < 1.2 Å, respectively. (f), Pore radius as a function of distance along the pore axis.
