The structural dynamics and molecular coupling in the slow inactivation of a prokaryotic voltage-gated sodium channel

Katsumasa Irie, Shuo Han, Sarah Applewhite, Yuki K. Maeda, Joshua Vance, Shizhen Wang

This study uses smFRET to reveal conformational changes in the prokaryotic NavAb channel during slow inactivation, identifying key residues that coordinate structural transitions.
