Fig. 5. Details of the SUN2 cation loop.

Fig. 5.

(a) Detailed view of the canonical potassium coordination in the cation loop, illustrated using the SUN2-KASH3 coordinates. 2Fo-Fc electron density map contoured at 1.5σ.

(b) The SUN2-KASH4 complex constitutes an exception, as it shows two water molecules positioned in the area that is typically occupied by a potassium ion. 2Fo-Fc electron density map contoured at 1.5σ.
