WebThe induction of CspA is mainly due to an increase in mRNA stability. Its half-life is 12 s at 37°C, but between 15 min and 30 min at 15°C in E. coli (Tanabe et al., 1992; Jiang et al., 1993; Fang et al., 1997; Gualerzi et al., 2003). If the coding region of cspA is fused to the constitutive promoter lpp, it is still cold inducible. This ... WebIn addition to the dramatic induction of the cspA mRNA amount upon cold shock, the mRNA is highly translatable at low temperature, whereas the translation of mRNAs for non-cold shock proteins is severely hampered in the acclimation phase.
