Deprotonation by Dehydration: The Origin of Ammonium Sensing in the AmtB Channel
Figure 5
AmtB Is Structurally Invariant Regardless of Its Occupied State
Structural alignment of channels occupied solely at site Am2 (silver), Am3 (red), and Am4 (blue). The window shows a closeup of the aligned binding sites. Slight differences are seen between each structure, but are within positional fluctuations.
