The Chaperonin GroEL Is Destabilized by Binding of ADP [PDF]

open access: yesJournal of Biological Chemistry, 1995
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]

open access: yesPLoS ONE, 2011
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.

The Functional Differences between the GroEL Chaperonin of Escherichia coli and the HtpB Chaperonin of Legionella pneumophila Can Be Mapped to Specific Amino Acid Residues

open access: yesBiomolecules, 2021
Group I chaperonins are a highly conserved family of essential proteins that self-assemble into molecular nanoboxes that mediate the folding of cytoplasmic proteins in bacteria and organelles.

A structural model for GroEL–polypeptide recognition [PDF]

open access: yesProceedings of the National Academy of Sciences, 1997
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]

open access: yesPLoS Genetics, 2013
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 ...

GroEL-Proteotyping of Bacterial Communities Using Tandem Mass Spectrometry

open access: yes, 2023
Profiling bacterial populations in mixed communities is a common task in microbiology. Sequencing of 16S small subunit ribosomal-RNA (16S rRNA) gene amplicons is a widely accepted and functional approach but relies on amplification primers and cannot ...

Back to GroEL-Assisted Protein Folding: GroES Binding-Induced Displacement of Denatured Proteins from GroEL to Bulk Solution

open access: yesBiomolecules, 2020
The main events in chaperone-assisted protein folding are the binding and ligand-induced release of substrate proteins. Here, we studied the location of denatured proteins previously bound to the GroEL chaperonin resulting from the action of the GroES co-

In vivo client proteins of the chaperonin GroEL-GroES provide insight into the role of chaperones in protein evolution

open access: yesFrontiers in Molecular Biosciences, 2023
Protein folding is often hampered by intermolecular protein aggregation, which can be prevented by a variety of chaperones in the cell. Bacterial chaperonin GroEL is a ring-shaped chaperone that forms complexes with its cochaperonin GroES, creating ...
