Exploring the Role of Bacterial Translation Factors in Metabolism and Stress Resistance

点击翻译按钮获取中文摘要

Bacteria are living cells that routinely encounter stressful situations and must adapt to survive. Stresses can include acids, detergents, antibiotics, heat, too much salt, toxic metals, and the immune systems of animals that they infect. Bacterial cells can do many things to protect themselves from such stresses including detoxifying or eliminating the cause of stress or by changing some aspect of their physiology (not unlike how a human sweats when they are hot). Not all environments are equal and the way a bacterial cell survives in one environment may be detrimental in another. Bacteria have therefore evolved to link particular stress responses to cues they detect in their local environment. The details of what signals are being sensed and exactly how this information is integrated into an effective response is the focus of this research.
