Abstract
A polyamine‐auxotrophic mutant of E. coli was cultivated in the presence or absence of putrescine and submitted to heat shock over 3 different ranges of temperature. In all cases, protein synthetic capacity measured in comparison to that of cultures at the preshift temperature was much higher in polyamine‐depleted bacteria under thermic stress. Addition of putrescine only before the shift‐up was able to restore gradually normal control of the relative protein synthetic capacity.Keywords
