Based on the electron crystallographic structure of AQP1, the hydrogen-bond isolation mechanism was proposed to explain why AQPs are impermeable to protons despite their very fast water conduction. The mechanism by which AQPs exclude protons remained controversial, however. Here we present the structure of AQP4 at 2.8 A resolution obtained by electron crystallography of double-layered two-dimensional crystals. The resolution has been improved from the previous 3.2 A, with accompanying improvement in data quality resulting in the ability to identify individual water molecules. Our structure of AQP4, the predominant water channel in the brain, reveals eight water molecules in the channel. The arrangement of the waters provides support for the hydrogen-bond isolation mechanism. Our AQP4 structure also visualizes five lipids, showing that direct interactions of the extracellular surface of AQP4 with three lipids in the adjoining membrane help stabilize the membrane junction."xsd:string |
