Understanding how the divisome is assembled in Chlamydia trachomatis, a bacterial pathogen, is crucial since this bacterium has a non-canonical cell wall and lacks the master regulator of cell division, FtsZ. This important study shows that a DNA translocase, FtsK, is an early and essential component of the Chlamydia trachomatis divisome. The evidence presented is convincing, leveraging the elegant use of genetics and fluorescence microscopy. As this role of FtsK is distinct relative to most other bacteria, these findings should be of significant interest to bacterial cell biologists.
