Abstract

The paper "Cell wall damage reveals spatial flexibility in peptidoglycan synthesis and a nonredundant role for RodA in mycobacteria" by Melzer et al. (E. S. Melzer, T. Kado, A. Garcia-Heredia, K. R. Gupta, et al., J Bacteriol 204:e00540-21, 2022, https://doi.org/10.1128/JB.00540-21) presents several new observations about the localization and function of cell wall enzymes in Mycobacterium smegmatis and their responses to stress. This work illustrates some important aspects of cell wall physiology in mycobacteria and also points to a new model for how peptidoglycan synthesis may be organized in pole-growing bacteria.
