Fig. 4: Unique water molecules and two Thr residues in the Lsi1 structure.
From: Structural basis for high selectivity of a rice silicon channel Lsi1
Hydrogen bonding interactions between the two water molecules comprising SF (Wat3 and Wat9) and TMs (TM1 and TM2) are shown with view directions facing the channel (a) or from the extracellular side (b). c A panel is showing the positions of Thr65 and Thr181. Hydrogen bond interactions that make the oxygen atoms of the waters pointing towards the channel are shown in yellow dashes.
