Cap-tivating findings provide insight into bacterial cell division.

In most bacteria, cell division is orchestrated by the tubulin homolog FtsZ. To ensure the correct placement of the division machinery, FtsZ activity needs to be tightly regulated. Corrales-Guerrero et al. now describe the molecular details of how MipZ, an alphaproteobacterial regulator, interacts with FtsZ to promote proper cell division.
