In an attempt to better understand FtsZ’s role during constriction, we are currently developing a method to rapidly disassemble the Z-ring at different time points over the course of the cell cycle and examine the consequences in the localization, function and dynamics of other divisome components. Our method uses variants of a pair of proteins, CRY2 and CIB1, isolated from Arabidopsis thaliana. Fusions of these proteins have been shown to rapidly dimerize upon irradiation with 488nm light in mammalian cells. To our knowledge, this system has yet to be applied in bacteria and may represent an effective method to shed light on a number of questions.
