CueR activates transcription through a DNA distortion mechanism.

Chengli Fang, Steven J Philips, Xiaoxian Wu, Kui Chen, Jing Shi, Liqiang Shen, Juncao Xu, Yu Feng, Thomas V O'Halloran, Yu Zhang,

The MerR-family transcription factors (TFs) are a large group of bacterial proteins responding to cellular metal ions and multiple antibiotics by binding within central RNA polymerase-binding regions of a promoter. While most TFs alter transcription through protein-protein interactions, MerR TFs are capable of reshaping promoter DNA. To address the question ... Read more >>

Crl activates transcription by stabilizing the active conformation of the master stress factor σS

Juncao Xu, Kaijie Cui, Liqiang Shen, Jing Shi, Lingting Li, Linlin You, Chengli Fang, Guoping Zhao, Yu Feng, Bei Yang, Yu Zhang,

SUMMARY σ S is a master transcription initiation factor that protects bacterial cells from various harmful environmental stresses and antibiotic pressure. Although its mechanism remains unclear, it is known that full activation of σ S -mediated transcription requires a σ S -specific activator, Crl. In this study, we determined a ... Read more >>
