PhD candidate Chris Hamm brings a huge amount of microfluidics-based experimental work to fruition in a new publication about how different RsbR proteins influence the sigma-B response mediated by the stressosome in different stressors. He shows that RsbRA always shows a transient response, irrespective of stressor identity, but that other RsbR paralogs show different responses to different stressors. Hybrid fusion proteins show that both halves of RsbRA are required for its characteristic transient response. He was assisted in this work by undergraduate Dax Butler. Their work is in press at mBio as of November 2022. Congratulations, gentlemen!
