Paper of the month: February 2015

To proliferate efficiently, cells must co-ordinate cell division with chromosome segregation. In B. subtilis, the nucleoid occlusion protein Noc binds to specific DNA sequences scattered around the chromosome and helps to protect genomic integrity by coupling the initiation of division to the progression of chromosome replication and segregation. However, how it inhibits division has remained unclear. Now, Adams et al. from the lab of Jeff Errington demonstrate that Noc associates with the cell membrane via an N-terminal amphipathic helix. Importantly, the membrane-binding affinity of this helix is weak and requires the assembly of nucleoprotein complexes, thus establishing a mechanism for DNA-dependent activation of Noc. Furthermore, division inhibition by Noc requires recruitment of Noc binding site DNA to the cell membrane and is dependent on its ability to bind DNA and membrane simultaneously. The results suggest a simple model in which the formation of large membrane-associated nucleoprotein complexes physically occludes assembly of the division machinery.
