The fact that bacteria spatially control the position of the cell wall machinery during the cell cycle was first recognised in the 1960s. However the underlying mechanism has remained a topic for debate due to the absense of any clear molecular insights. The discovery of a protein that is central to shutting of cell wall synthesising enzymes in the model microorganism Bacillus subtilis now shines a light on a molecular switch that shuttles Penicillin Binding Protein 1 between elongation and cell division.
This is recognised by the publication of Edwards et. al being picked upas a "Research Highlight" by Nature Reviews Microbiology.
