We may notice the presence of a glycine (Gly67) which brings four carbonyl oxygen atoms, more inward oriented, able to bind with water molecules. This create an environement which can chelate K+ and Rb+ ions, but avoid the binding of Na+. | We may notice the presence of a glycine (<scene name='60/604488/Gly67/1'>TextToBeDisplayed</scene>) which brings four carbonyl oxygen atoms, more inward oriented, able to bind with water molecules.

Moreover, thanks to a space intercation between Asp 66 and Gly67, the external site has a higher affinity for divalent cations such as Ca2+ and Ba2+ rather than monovalent such as K+ and Rb+ <ref> PMID: 17878296</ref>. | Moreover, thanks to a space intercation between Asp 66 and Gly67, the external site has a higher affinity for divalent cations such as Ca2+ and Ba2+ rather than monovalent such as K+ and Rb+ <ref> PMID: 17878296</ref>. | ||
