Potassium channels rapidly move K+ ions across cell membranes while blocking Na+, but how these two effects are achieved simultaneously has remained unclear. Now, extensive molecular simulations show a single mechanism that features fully dehydrated ions can explain both rapid transport and impeccable selectivity.

钾通道在阻断 Na+ 的同时快速移动 K+ 离子穿过细胞膜，但如何同时实现这两种效果仍不清楚。现在，广泛的分子模拟表明，具有完全脱水离子的单一机制可以解释快速传输和无可挑剔的选择性。
