Biomakromolekulare Nanoröhren spielen eine wichtige physiologische Rolle für transmembranäre Transportvorgänge von Ionen/Molekülen im intrazellulären Transport und in der interzellulären Kommunikation. Während genetisch kodierte Protein‐Nanoröhren das In‐vivo‐Geschehen dominieren, findet seit Anbruch der strukturellen DNA‐Nanotechnologie die In‐vitro‐Konstruktion biomimetischer DNA‐Nanoröhren zunehmende...
Reconfiguration of membrane protein channels for gated transport is highly regulated under physiological conditions. However, a mechanistic understanding of such channels remains challenging owing to the difficulty in probing subtle gating‐associated structural changes. Herein, we show that charge neutralization can drive the shape reconfiguration of a biomimetic 6‐helix bundle DNA nanotube (6HB)...
