WebDec 21, 2001 · Introduction. In response to temperature downshift, Escherichia coli cells enter a growth lag period during which a number of genes are induced, in contrast to a severe arrest of general proteins synthesis (Jones et al., 1987).Among the cold‐shock proteins the most prominent is CspA, which is grossly overproduced after cold shock … 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 …
