• PubMed Abstract: 
  

  The universal stress proteins (USP) family member UspE is a tandem-type USP that consists of two Usp domains. The UspE expression levels of the Escherichia coli (E. coli) become elevated in response to oxidative stress and DNA damaging agents, including exposure to mitomycin C, cadmium, and hydrogen peroxide. It has been shown that UspA family members are survival factors during cellular growth arrest. The structures and functions of the UspA family members control the growth of E. coli in animal hosts. While several UspA family members have known structures, the structure of E. coli UspE remains to be elucidated.
