The Elongasome in rod-shaped bacteria is primarily composed of:
In rod shaped bacteria elongation before division mediated by elongasome or Rod complex distinct from divisome. Core organizer is MreB actin homolog that forms short dynamic patches moving around cell circumference perpendicular to long axis. Motion driven by peptidoglycan synthesis not treadmilling alone, powered by RodA transglycosylase activity. MreB interacts with integral membrane proteins MreC, MreD, RodZ cytoplasmic tail linking to peptidoglycan synthases RodA transglycosylase from SEDS family polymerizing lipid II glycan strands and PBP2a PBP2 transpeptidase crosslinking peptides.
