WebbThe Psp response was discovered by Peter Model and his colleagues at the Rockefeller University in New York City. They noticed that infection of Escherichia coli cells by the filamentous phage f1 and production of the phage-encoded secretin (a pore-forming protein) caused massive production of a bacterial protein they called PspA [ 8 ]. WebbThe temperature-sensitive bacteriophage λ c 1857 repressor protein rapidly renatures after thermal inactivation. E. coli mutants in the heat shock protein genes dnaK, dnaJ , and grpE do not efficiently reactivate heat-denatured repressor. Our results suggest that protein refolding is promoted by heat shock proteins and that such a process is the basis of the …
