antitoxin module from Escherichia coli O157: H7. Although this module's toxin, antitoxin, and
toxin-antitoxin complex have been more thoroughly investigated, little remains known about
its transcription regulator PaaR2. Using a wide range of biophysical techniques (circular
dichroism spectroscopy, size-exclusion chromatography-multiangle laser light scattering,
dynamic light scattering, small-angle x-ray scattering, and native mass spectrometry), we …
