Thermodynamic stability of the transcription regulator PaaR2 from Escherichia coli O157:H7 University of Antwerp Flanders Institute for Biotechnology Vrije Universiteit Brussel KU Leuven
PaaR2 is a putative transcription regulator encoded by a three-component parDE-like toxin-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 ...
