The Mycobacterium tuberculosis sRNA F6 Modifies Expression of Essential Chaperonins, GroEL2 and GroES

open access: yesMicrobiology Spectrum, 2021
Almost 140 years after the identification of Mycobacterium tuberculosis as the etiological agent of tuberculosis, important aspects of its biology remain poorly described.

The Legionella pneumophila chaperonin – an unusual multifunctional protein in unusual locations

open access: yesFrontiers in Cellular and Infection Microbiology, 2011
The L. pneumophila chaperonin, HtpB, was discovered as a highly immunogenic antigen, only a few years after the identification of L. pneumophila as the causative agent of Legionnaires’ disease.

Reconstitution of Pure Chaperonin Hetero-Oligomer Preparations in Vitro by Temperature Modulation

open access: yesFrontiers in Molecular Biosciences, 2018
Chaperonins are large, essential, oligomers that facilitate protein folding in chloroplasts, mitochondria, and eubacteria. Plant chloroplast chaperonins are comprised of multiple homologous subunits that exhibit unique properties.

Proteostatic Regulation of MEP and Shikimate Pathways by Redox-Activated Photosynthesis Signaling in Plants Exposed to Small Fungal Volatiles

open access: yesFrontiers in Plant Science, 2021
Microorganisms produce volatile compounds (VCs) with molecular masses of less than 300 Da that promote plant growth and photosynthesis. Recently, we have shown that small VCs of less than 45 Da other than CO2 are major determinants of plant responses to ...

Mechanism and functional analysis of chaperonins of Mycobacterium marinum [PDF]

open access: yes, 2023
Mycobacterial chaperonins have been demonstrated to play an important role in immunomodulation. Both the chaperonins of M. tuberculosis have been revealed to be involved directly or indirectly in pathology of tuberculosis.

Structural basis for the structural dynamics of human mitochondrial chaperonin mHsp60

open access: yesScientific Reports, 2021
Human mitochondrial chaperonin mHsp60 is essential for mitochondrial function by assisting folding of mitochondrial proteins. Unlike the double-ring bacterial GroEL, mHsp60 exists as a heptameric ring that is unstable and dissociates to subunits.

The dynamic conformational cycle of the group I chaperonin C-termini revealed via molecular dynamics simulation.

open access: yesPLoS ONE, 2015
Chaperonins are large ring shaped oligomers that facilitate protein folding by encapsulation within a central cavity. All chaperonins possess flexible C-termini which protrude from the equatorial domain of each subunit into the central cavity ...

The VHL tumor suppressor at the crossroad of protein folding, aggregation, and cancer

open access: yesMolecular Oncology, EarlyView.
Mutations, environmental stress, and chaperone dysfunction can destabilize pVHL, promoting its conversion from the native folded state into amyloid‐like assemblies. This transition may contribute to protein storage, cell dormancy, survival, and drug resistance.

Dynamics, flexibility, and allostery in molecular chaperonins [PDF]

open access: yes, 2015
The chaperonins are a family of molecular chaperones present in all three kingdoms of life. They are classified into Group I and Group II. Group I consists of the bacterial variants (GroEL) and the eukaryotic ones from mitochondria and chloroplasts ...

Cryo-EM structure of human mitochondrial HSPD1

open access: yesiScience, 2021
Summary: Chaperonins play an important role in folding newly synthesized or translocated proteins in all organisms. The bacterial chaperonin GroEL has served as a model system for the understanding of these proteins.
