This positive section is characteristic of trans-membrane proteins as a means of achieving proper orientation within the cell membrane. Binding sites A, B, and C, as well as the CTDs of both monomers, all possess a high negative charge relative to the other charges present, facilitating the binding and releasing of Zn²⁺ ions. The two CTDs are held together by the charge interlock and hydrophobic interactions of the TMDs, despite their electrostatic repulsion. Upon the release of Zn²⁺ ions, the CTDs undergo alterations to electronegativity, which enables domain separation.
