Chaperonin GroEL Reassembly: An Effect of Protein Ligands and Solvent Composition
Chaperonin GroEL is a complex oligomeric heat shock protein (Hsp60) assisting the correct folding and assembly of other proteins in the cell. An intriguing question is how GroEL folds itself.

The Chaperonin GroEL Is Destabilized by Binding of ADP [PDF]
The urea-induced dissociation and subsequent conformational transitions of the nucleotide-bound form of GroEL were studied by light scattering, 4,4'-bis(1-anilino-8- naphthalenesulfonic acid) binding, and intrinsic tyrosine fluorescence. Magnesium ion alone (10 mM) stabilizes GroEL and leads to coordination of the structural transitions monitored by ...

Probing the functional mechanism of Escherichia coli GroEL using circular permutation. [PDF]
BACKGROUND: The Escherichia coli chaperonin GroEL subunit consists of three domains linked via two hinge regions, and each domain is responsible for a specific role in the functional mechanism.

Ligands regulate GroEL thermostability
Escherichia coli heat‐shock proteins GroEL and GroES stimulate (in an ATP‐dependent manner) the folding of various proteins. In this study scanning microcalorimetry was applied to investigate GroEL thermostability in the presence of its ligands. Mg2+ and K+ ions stabilize while ADP destabilizes the GroEL molecule against the action of temperature ...

A structural model for GroEL–polypeptide recognition [PDF]
A monomeric peptide fragment of GroEL, consisting of residues 191–376, is a mini-chaperone with a functional chaperoning activity. We have solved the crystal structure at 1.7 Å resolution of GroEL(191–376) with a 17-residue N-terminal tag. The N-terminal tag of one molecule binds in the active site of a neighboring molecule in the crystal. This appears

Mechanisms involved in the functional divergence of duplicated GroEL chaperonins in Myxococcus xanthus DK1622. [PDF]
The gene encoding the GroEL chaperonin is duplicated in nearly 30% of bacterial genomes; and although duplicated groEL genes have been comprehensively determined to have distinct physiological functions in different species, the mechanisms involved have ...
