Figure 8.

(a) An electrostatic potential surface of wildtype solute carrier family 4, sodium borate transporter, member 11 protein indicating amino acid residue ARG at position 831/804. (b) An electrostatic potential surface of mutant-type protein indicating amino acid residue CYS at position 831/804. In the colour legend, the red colour indicates negative potential, the blue colour indicates positive potential of the protein surface and the white regions correspond to fairly neutral potentials. Yellow arrow indicates towards the mutation site at position 831/804.
