Formation of the chaperonin complex studied by 2D NMR spectroscopy. [PDF]
We studied the interaction between GroES and a single-ring mutant (SR1) of GroEL by the NMR titration of 15N-labeled GroES with SR1 at three different temperatures (20, 25 and 30°C) in the presence of 3 mM ADP in 100 mM KCl and 10 mM MgCl2 at pH 7.5.

Identification of elements that dictate the specificity of mitochondrial Hsp60 for its co-chaperonin. [PDF]
Type I chaperonins (cpn60/Hsp60) are essential proteins that mediate the folding of proteins in bacteria, chloroplast and mitochondria. Despite the high sequence homology among chaperonins, the mitochondrial chaperonin system has developed unique ...

The Cowdria ruminantium groE operon [PDF]
A Cowdria ruminantium genomic DNA library was constructed in the expression vector lambda ZAPII, and an immunoreactive clone, designated lambda Cr9.4, was isolated by screening with serum from a C. ruminantium-infected goat. Sequencing of the insert from this clone revealed two open reading frames, encoding peptides of 10462 and 58697 kDa respectively.

GroES and the chaperonin‐assisted protein folding cycle: GroES has no affinity for nucleotides [PDF]
The E. coli chaperonin proteins, GroEL and GroES, assist in folding newly synthesized proteins. GroES is necessary for GroEL‐assisted folding under conditions where the substrate protein cannot spontaneously fold. On the basis of photolabelling of GroES with 8‐azido‐ATP, a role for nucleotide binding to GroES in chaperonin function was suggested ...

ATTRACT-EM: a new method for the computational assembly of large molecular machines using cryo-EM maps. [PDF]
Many of the most important functions in the cell are carried out by proteins organized in large molecular machines. Cryo-electron microscopy (cryo-EM) is increasingly being used to obtain low resolution density maps of these large assemblies.

Stability of the chaperonin system GroEL-GroES under extreme environmental conditions.
The chaperonin system GroEL-GroES is present in all kingdoms of life and rescues proteins from improper folding and aggregation upon internal and external stress conditions, including high temperatures and pressures.

Ligand Binding Introduces Significant Allosteric Shifts in the Locations of Protein Fluctuations
Allostery is usually considered to be a mechanism for transmission of signals associated with physical or dynamic changes in some part of a protein. Here, we investigate the changes in fluctuations across the protein upon ligand binding based on the ...
