The production of CdiA2-CT in Escherichia coli induces DNA damages. Time-lapse fluorescence microscopy of the recombinant RecA-GFP protein produced by E. coli MG1655 strain after induction of the CdiA2-CT in the absence or in the presence of its cognate CdiI2 immunity protein. White arrows indicate examples of bundles of RecA-GFP. The scale bar corresponds to 5 μm. GFP, green fluorescent protein.
