Isolation and Characterisation of Mutants of GroEL that are Fully Functional as Single Rings

A key aspect of the reaction mechanism for the molecular chaperone GroEL is the transmission of an allosteric signal between the two rings of the GroEL complex. Thus, the single-ring mutant SR1 is unable to act as a chaperone as it cannot release bound substrate or GroES. We used a simple selection...
