The research in our laboratory aims at understanding how the elements of the bacterial division machinery - the divisome - work together as an integrated system to fulfill its essential function. To address these questions we develop and applied novel biochemical reconstitution approaches to assemble the minimal set of proteins needed to initiate division (the proto-ring complex) in systems that reproduce the spatio-temporal organization of the divisome at the cellular membrane and the crowded/confined intracellular space. This integrative strategy, combining quantitative and synthetic approaches, will help to complete our knowledge on how bacterial division works and will open new horizons to pharmacological applications.
