Stress-mediated programmed cell death (PCD) in bacteria has recently attracted attention, largely because it raises novel possibilities for controlling pathogens. How PCD in bacteria is regulated to avoid population extinction from transient, moderate stress remains a central question. We report that the YihE protein kinase is a key regulator that protects Escherichia coli from antimicrobial and environmental stressors by antagonizing the MazEF toxin-antitoxin module. YihE was linked to a reactive oxygen spec…
scite is a Brooklyn-based startup that helps researchers better discover and evaluate scientific 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 researchers from dozens of countries and is funded in part by the National Science Foundation and the National Institute of Drug Abuse of the National Institutes of Health.
