Abstract:The stressosome is a protein complex that senses environmental stresses and mediates the stress response in several Gram-positive bacteria, through the activation of the alternative sigma factor SigB. The stressosome locus is found in 44% of Gram-negative Vibrio vulnificus isolates. However, V. vulnificus does not possess SigB. Nonetheless, in nutrient-limited media, the stressosome modulates gene transcription and bacterial behaviour.
In this work, the expression of the stressosome genes was proven during sta… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
