WebIntroduction. Upon temperature downshift from 37°C to 10°C, a number of proteins are induced in Escherichia coli (Jones et al., 1987).Among them, CspA has been identified as the major cold-shock protein whose production reaches more than 10% of total cellular protein synthesis (Goldstein et al., 1990).In contrast to heat shock, which induces a … WebJul 22, 2016 · Transient cspA mRNA stabilization due to low temperature is probably an important factor in the induction of CspA during cold shock (Phadtare and Severinov, 2005).
