How Salmonella Works Under Osmotic and Desiccation Stresses

open access: yesComprehensive Reviews in Food Science and Food Safety, Volume 25, Issue 3, May 2026.
ABSTRACT Salmonella remains one of the leading threats in foods with reduced water activity, where it can survive for long periods and cause outbreaks. Its persistence stems from a wide array of adaptive strategies shaped by the selective pressures imposed by low‐moisture foods.

GroEL actively stimulates folding of the endogenous substrate protein PepQ

open access: yesNature Communications, 2017
In the prevailing model for assisted protein folding, chaperonins act passively by preventing protein aggregation. Here, the authors use single-molecule fluorescence measurements and cryo-electron microscopy and show that theE.

Mechanisms of a Mycobacterium tuberculosis Active Peptide

open access: yesPharmaceutics, 2023
Multidrug-resistant tuberculosis (MDR) continues to pose a threat to public health. Previously, we identified a cationic host defense peptide with activity against Mycobacterium tuberculosis in vivo and with a bactericidal effect against MDR M ...

High salt-induced conversion of Escherichia coli GroEL into a fully functional thermophilic chaperonin [PDF]

open access: yes, 2000
The GroE chaperonin system can adapt to and function at various environmental folding conditions. To examine chaperonin-assisted protein folding at high salt concentrations, we characterized Escherichia coli GroE chaperonin activity in 1.2 M ammonium ...

Clostridioides difficile‐Derived Extracellular Vesicles Induce Proinflammatory Responses in Macrophages

open access: yesJournal of Extracellular Vesicles, Volume 15, Issue 4, April 2026.
ABSTRACT Clostridioides difficile (CD) is a leading cause of antibiotic‐associated diarrhoea in both hospitalized and non‐hospitalized patients. This study explores the role of extracellular vesicles (EVs) derived from Clostridioides difficile strain 630 (CD630‐EVs), which released spherical EVs during in vitro culture, in modulating pro‐inflammatory ...

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 ...

Acetyl‐Phosphate Dependent Protein Acetylation in Neisseria gonorrhoeae

open access: yesMicrobiologyOpen, Volume 15, Issue 2, April 2026.
The role of acetyl‐phosphate‐dependent non‐enzymatic protein acetylation in Neisseria gonorrhoeae was investigated through the deletion of the phosphotransacetylase (pta) and the acetate kinase (ackA) genes, this led to a decrease and increase in protein acetylation, respectively.

cpnDB: A Chaperonin Sequence Database [PDF]

open access: yesGenome Research, 2004
Type I chaperonins are molecular chaperones present in virtually all bacteria, some archaea and the plastids and mitochondria of eukaryotes. Sequences of cpn60 genes, encoding 60-kDa chaperonin protein subunits (CPN60, also known as GroEL or HSP60), are useful for phylogenetic studies and as targets for detection and identification of organisms ...

The Cpn10(1) co-chaperonin of A. thaliana functions only as a hetero-oligomer with Cpn20. [PDF]

open access: yesPLoS ONE, 2014
The A. thaliana genome encodes five co-chaperonin homologs, three of which are destined to the chloroplast. Two of the proteins, Cpn10(2) and Cpn20, form functional homo-oligomers in vitro.
