Abstract/OtherAbstract:
Prefoldin is a jellyfish-shaped hexameric chaperone that captures a protein-folding intermediate and transfers it to the group II chaperonin for correct folding. In this work, we characterized the organic solvent tolerance of Escherichia coli cells that overexpress prefoldin and group II chaperonin from a hyperthermophilic archeaum, Pyrococcus horikoshii OT3. The colony-forming efficiency of E. coli cells overexpressing prefoldin increased by 1,000-fold and decreased the accumulation of intracellular organic solvent. The effect was impaired by deletions of the region responsible for the chaperone function of prefoldin. Therefore, we concluded that prefoldin endows E. coli cells by preventing accumulation of intracellular organic solvent through its molecular chaperone activity.
