Structural and functional insights into multiple BAM-bound conformations of BepA enabling substrate triage at the outer membrane

Ryoji Miyazaki, Mai Kimoto, Hidetaka Kohga…·Tomoya Tsukazaki

This study reports cryo-EM structures of BAM-BepA complexes and identifies loop conformations that regulate BepA's dual function in substrate triage.

Escherichia coli S2P family intramembrane protease RseP is engaged in the regulated sequential cleavages of FecR in the ferric citrate signaling

Tatsuhiko Yokoyama, Tomoya Niinae, Kazuya Tsumagari…·Yoshinori Akiyama

This study identifies RseP as an intramembrane protease that cleaves FecR, a regulator of ferric citrate uptake, revealing a novel role in iron homeostasis in E. coli.
