Distinct modes of redox-mediated DegP activation govern its role as a general protease

Deeptodeep Roy, Ardra Nandakumar, Rachna Chaba

This study identifies two distinct redox-mediated mechanisms that activate DegP, a protease in E. coli, enabling it to function as a general protease under various stress conditions.

An envelope stress response governs long-chain fatty acid metabolism via a small RNA to maintain redox homeostasis in Escherichia coli

Megha Shrivastava, Manmehar Kaur, Liz Maria Luke, Richa Ashok Kakkar, Deeptodeep Roy, Shivam Singla, Vanshika Sharma, Gaurav Sharma, Rachna Chaba

This paper shows that E. coli uses a small RNA, CpxQ, to regulate long-chain fatty acid metabolism and maintain redox homeostasis by suppressing LCFA processing and increasing ubiquinone levels.
