An ART-fold Rhs toxin from Pluralibacter gergoviae defines Tne5, a new clade of NAD(P)⁺ glycohydrolases effectors

Jonas B. Desjardins, Martin Durrmeyer, Eric Cascalès

The paper identifies a new T6SS effector from Pluralibacter gergoviae that depletes NAD and NADP, defining a new clade of NAD(P) glycohydrolases called Tne5.

Molecular bases for the loss of type VI secretion system activity during enteroaggregative E. coli experimental evolution

Boris Taillefer, Jonas B. Desjardins, Eric Cascalès

This study uses experimental evolution to show that T6SS activity is lost in EAEC when grown with immune cells, identifying mutations and a novel RfaH-dependent regulatory mechanism.
