The paper investigates the conformational switch of ExbD in the Ton system and its role in nutrient uptake, revealing the anchoring function of peptidoglycan and proposing a mechanistic model.

The paper uses molecular dynamics simulations to study the interaction between a heme transporter and a TonB-like protein in E. coli, revealing dynamic interactions and validating them experimentally.

The paper determines the cryo-EM structures of ExbBSm and ExbB-ExbDSm complex, identifies key residues for function and interaction with TonB/HasB, and reveals the role of ExbBSm extension in heme acquisition.
