"RETRACTED ARTICLE: Vibrio parahaemolyticus RhsP represents a widespread group of pro-effectors for type VI secretion systems

Abstract

It is unclear how Rhs toxins lacking a PAAR motif are secreted by Type VI secretion systems. Here, the authors show for one of these proteins that the mechanism requires removal of an N-terminal fragment by auto-proteolysis, followed by interaction with a PAAR protein and then secretion.
