The SF of NavAb N49K and S178G
NK
(LivAb
NK
) mutants. Side view of the residues 175–179th constituting the SF of N49K (left, PDB code 8H9W) and S178GNK (LivAbNK) (right, PDB code 9UC3). The red dashed lines represent the hydration water-exchange sites through which ions pass, formed by the oxygen atoms of the main and side chains of the SF.
