Asymmetric peptidoglycan editing generates cell curvature in Bdellovibrio predatory bacteria

Abstract

Cells of the predatory bacterium Bdellovibrio bacteriovorus, which invades and replicates within the periplasm of other bacteria, have a characteristic curved rod shape. Here, Banks et al. show that a peptidoglycan hydrolase is required for the curved shape, and this facilitates invasion of prey cells.
