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 … WebInterestingly, the optimal temperature ranges for their induction are different: CspA induction occurs over the broadest temperature range (30 to 10°C), CspI induction occurs over the narrowest and lowest temperature range (15 to 10°C), and CspB and CspG occurs at temperatures between the above extremes (20 to 10°C).
