A new family of Type VI secretion system-delivered effector proteins displays ion-selective pore-forming activity

Giuseppina Mariano, Katharina Trunk, David J. Williams…·Sarah J. Coulthurst

The paper identifies Ssp6 as an ion-selective pore-forming toxin delivered by the T6SS of Serratia marcescens, showing it causes membrane depolarization and increased permeability.
