RpoH(σ32)是E.coli拥有的七个转录调控因子之一,可在E.coli细胞受到热击、高渗、氧化、干燥、抗生素等环境压力时通过诱导热休克反应提高细胞的生存能力和适合度。因此,与RpoS一样,RpoH也是一个一般压力反应调控因子。RpoH具有广泛的调控作用,可在温度升高时控制数百个基因的转录,这些基因编码的功能涉及蛋白质稳态维...
Most types ofE. colibacteria aren't dangerous, but a few are harmful. The EHEC/STEC type is responsible for mostE. coliinfections that causediarrheain people. You can lessen your chances of getting an infection by always washing your hands after using the toilet, handling food (especially raw...
The meaning of E. COLI is an enterobacterium (Escherichia coli) that is used in public health as an indicator of fecal pollution (as of water or food) and in medicine and genetics as a research organism and that occurs in various strains that may live as
【摘要】RpoS(σs或σ38)是迄今发现的E.coli的7种转录起始因子之一,可在E.coli生长率下降、进入静止期或受到饥饿、热击、低温、高渗、氧化等环境压力时被诱导表达,从而或直接或间接的促进或抑制上千个基因的转录,以使E.coli能够对(现存和未来可能遇到的)多种环境压力做出响应。RpoS主导的一般压力反应伴有能耗且...
Because E. coli contamination requires very few bacteria, contaminated meat looks and smells normal. So, if you’re a carnivore, the surest way of avoiding a close encounter with E. coli is to cook your meat thoroughly – and have your steak tartare well-done. E. gads!
