1. The dimer is held together via a complex salt bridge network. 2. This leads to destruction of salt bridge and structure destabilization. 3. The salt bridge formed is between the deprotonated Asp70 and protonated His31. 4. Certain salt bridges likely also play a role in thermostability. 5. The yellow line between Asp15 and Arg176 shows the salt bridge present. 6. Also, surface salt bridges , under certain conditions, can display a stabilizing effect. 7. The ionic nature is found in the salt bridge formed from Arg359 to the phosphate group. 8. To maintain the salt bridge , His31 will attempt to keep its proton as long as possible. 9. Completing the circuit and connecting the two chambers is a salt bridge or ion-exchange membrane. 10. The SHE electrode can be connected to any other electrode by a salt bridge to form a cell.
