VgrG proteins form the spike of the type VI secretion system (T6SS) syringe-like complex. VgrG3 of Vibrio cholerae degrades the peptidoglycan cell wall of rival bacteria via its C-terminal region (VgrG3C) through its muramidase activity. VgrG3C consists of a peptidoglycan-binding domain (VgrG3C(PGB)) and a putative catalytic domain (VgrG3C(CD)), and its activity can be inhibited by its immunity protein partner TsiV3 ...
