Conditions of forming protein complexes with GroEL can influence the mechanism of chaperonin-assisted refolding.


The interaction of GroEL with urea-unfolded dihydrofolate reductase (DHFR) has been studied in the presence of DHFR substrates by investigating the ability of GroES to release enzyme under conditions where a stable GroES-GroEL-DHFR ternary complex can be formed. In these circumstances, GroES could only partially discharge the DHFR if ADP was present in the… (More)
