WebJul 1, 1999 · 1 Introduction. When exponentially growing Escherichia coli cells are shifted from 37°C to low temperature, cells stop growing as the synthesis of most cellular proteins is either shut off or significantly reduced. This growth lag period is termed the acclimation phase, during which cold-shock proteins such as CspA , CspB , CspG and CspI are …

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 …
WebJan 15, 2010 · cspA and cspD mRNAs were analyzed by temperature gradient gel electrophoresis: (C) electrophoretic mobility in a 7.5% acrylamide gel of cspA mRNA (428 nt) and cspD mRNA (372 nt) as a … WebMar 15, 1999 · As with cspA mRNA, the cold induction of CspA also depended on the initial level of this protein in cells at different stages of growth and the maximum increment (30-fold) was seen in mid-to-late log cells . In all cases, however, the maximum level attained by CspA after cold shock (≈2% of total soluble protein) is such that the net …

WebMar 1, 2002 · Among them, CspA is the major cold shock protein because of its highest induction (more than 10% of the total cellular protein synthesis) after temperature downshift. The small RNA-binding protein CspA (molecular mass 7.4 kDa) was proposed to function as an RNA chaperone that facilitates translation by destabilizing mRNA …
WebA shift in growth temperature from 37° C to 15° C leads to a dramatic increase in the level of CspA, the major cold shock protein of Escherichia coli.To investigate the molecular basis of this induction, we considered the relevance of transcriptional and post-transcriptional controls by analyzing the steady-state levels of transcripts and the expression of reporter …
Webinduction/build-up of CspA after cold shock is transient, a much decreased but still significant new basal level of expression (see Fig. 3E) helps to maintain the high CspA concentration during steady growth at low temperature.
