Time-resolved emission spectroscopy to elucidate the functional nature of heat-stable transcription factor

A 22 kDa protein from Thermus thermophilus is characterised as a DNA binding transcription regulator and its function is established using the fluorescence spectroscopy technique. The steady-state fluorescence spectroscopy result shows significant binding of calf thymus DNA and protein molecule. To confirm, the DNA quenching effect in real-time, a time-resolved emission spectroscopy study was performed and the result shows good agreement with steady-state quenching analysis. © 2022 Wiley Periodicals LLC.
