摘要:
This protocol describes a method for verifying the specific transcription factor regulating glycerol dehydratase (GDH) expression in Klebsiella. DNA pull-down accompanied with mass spectrometry is used to screen and identify the transcription factor interacting with the promoter region of the key gene in Klebsiella. EMSA method is used to validate the specific binding of the transcription factor to the promoter region in vitro. In addition, the target DNA fragments are constructed by fusion PCR to prepare competent cells from Klebsiella for electrical transformation and further transformed to ...
