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.
