First 20 Years of Orbitrap Mass Spectrometry as the Mainstream Analytical Technique
Mass Spectrometry Reviews, EarlyView.ABSTRACT This review traces the first 20 years of Orbitrap mass spectrometry as a mainstream high‑resolution and accurate‑mass (HR/AM) technology. It outlines the historical development of the Orbitrap analyzer, the evolution of major instrument families, and the key technological innovations that enabled its widespread adoption. Particular emphasis is

In vivo activities of GroEL minichaperones [PDF]
Proceedings of the National Academy of Sciences, 1998 Fragments encompassing the apical domain of GroEL, called minichaperones, facilitate the refolding of several proteins in vitro without requiring GroES, ATP, or the cage-like structure of multimeric GroEL.

The Chaperonin GroEL: A Versatile Tool for Applied Biotechnology Platforms
Frontiers in Molecular Biosciences, 2018 The nucleotide-free chaperonin GroEL is capable of capturing transient unfolded or partially unfolded states that flicker in and out of existence due to large-scale protein dynamic vibrational modes.

Bacterial Heat Shock Protein GroEL (Hsp64) Exerts Immunoregulatory Effects on T Cells by Utilizing Apoptosis. [PDF]
PLoS ONE, 2016 Aggregatibacter actinomycetemcomitans (Aa) expresses a 64-kDa GroEL protein belonging to the heat shock family of proteins. This protein has been shown to influence human host cells, but the apoptotic capacity of the GroEL protein regarding T cells is ...

Gut microbiota dysbiosis and Long COVID susceptibility in chronic kidney disease
VIEW, EarlyView.This study investigated gut microbiota dysbiosis and its association with Long COVID susceptibility in 224 hemodialysis patients. We found that 35.3% of patients developed Long COVID, characterized by neurological symptoms and elevated inflammatory markers, accompanied by significant gut microbiota alterations including enriched proinflammatory taxa ...

GroEL/ES inhibitors as potential antibiotics [PDF]
Bioorganic & Medicinal Chemistry Letters, 2016 We recently reported results from a high-throughput screening effort that identified 235 inhibitors of the Escherichia coli GroEL/ES chaperonin system [Bioorg. Med. Chem. Lett.2014, 24, 786]. As the GroEL/ES chaperonin system is essential for growth under all conditions, we reasoned that targeting GroEL/ES with small molecule inhibitors could be a ...

Russian wheat aphid: a model for genomic plasticity and a challenge to breeders
Insect Science, EarlyView.Invasive foundress finds suitable habitat and reproduces through pathogenesis. Wingless females produce life offspring quickly, which leads to high population densities. High population densities result in competition, which may induce epigenetic changes and wing development for dispersal.

Novel cryo-EM structure of an ADP-bound GroEL–GroES complex
Scientific Reports, 2021 The GroEL–GroES chaperonin complex is a bacterial protein folding system, functioning in an ATP-dependent manner. Upon ATP binding and hydrolysis, it undergoes multiple stages linked to substrate protein binding, folding and release.
