Breaking barriers: transitioning from X-ray crystallography to cryo-EM for structural studies. [PDF]
This article describes the transition of the Glass laboratory from X‐ray crystallography to single‐particle cryo‐electron microscopy (cryo‐EM) for structural studies of ATAD2B, a large AAA+ ATPase‐ and bromodomain‐containing protein involved in chromatin regulation.

Structural and Computational Study of the GroEL–Prion Protein Complex
The molecular chaperone GroEL is designed to promote protein folding and prevent aggregation. However, the interaction between GroEL and the prion protein, PrPC, could lead to pathogenic transformation of the latter to the aggregation-prone PrPSc form ...

Porphyromonas gingivalis GroEL induces osteoclastogenesis of periodontal ligament cells and enhances alveolar bone resorption in rats. [PDF]
Porphyromonas gingivalis is a major periodontal pathogen that contains a variety of virulence factors. The antibody titer to P. gingivalis GroEL, a homologue of HSP60, is significantly higher in periodontitis patients than in healthy control subjects ...

Cryo-EM map interpretation and protein model-building using iterative map segmentation. [PDF]
A procedure for building protein chains into maps produced by single-particle electron cryo-microscopy (cryo-EM) is described. The procedure is similar to the way an experienced structural biologist might analyze a map, focusing first on secondary ...

Structural Plasticity and Noncovalent Substrate Binding in the GroEL Apical Domain. A study using electrospray ionization mass spectrometry and fluorescence binding studies [PDF]
Advances in understanding how GroEL binds to non-native proteins are reported. Conformational flexibility in the GroEL apical domain, which could account for the variety of substrates that GroEL binds, is illustrated by comparison of several independent ...

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 ...
