Elongasome

A protein complex that catalyzes peptidoglycan biosynthesis and is thereby involved in maintaining cell shape

Complex members

cell wall biosynthetic enzymes at the outer side of the membrane: penicillin-binding proteins
transmembrane proteins: MreC, MreD, RodA, RodZ
actin-like proteins at the inner surface of the membrane: MreB, MreBH, Mbl

Domínguez-Escobar et al. from Rut Carballido-Lopez' lab and Garner et al. report that movement of actin-like filaments is driven by the peptidoglycan elongation machinery. Both papers suggest that the MreB-like filaments serve to restrict the mobility of the peptidoglycan synthesizing machinery
