Binding of [Lys]-fullerene to the outer vestibule of NavAb. (A) Top view illustrating the four Met181 residues (shown in grey) coordinating the [Lys]-fullerene molecule. Note that the lysine side chains of the [Lys]-fullerene have been removed for clarity. (B) Side view illustrating the Met181 residues and Glu177 interaction with one of the lysine chains of the [Lys]-fullerene.
