Chaperonins are protein-folding machinery found in all cellular life. Chaperonin genes have been documented within a few viruses, yet, surprisingly, analysis of metagenome sequence data indicated that ...
In a new study in archaea (single-celled organisms without nuclei to enclose their genetic information), researchers have discovered how the Group II chaperonins close and open folding chambers to ...
Chaperonins are allosteric double-ring ATPases that mediate cellular protein folding. ATP binding and hydrolysis control opening and closing of the central chaperonin chamber, which transiently ...
Molecular chaperones traffic signaling proteins between cells in plant stem-cell maintenance pathway
Plant biologists have discovered that proteins called chaperonins are an indispensable factor in making possible cell-to-cell trafficking of signals that maintain stem cells and enable plants to grow.
Proteins are the molecular building blocks of life. In order to perform a multiplicity of functions in the cell, each protein must adopt a defined three-dimensional structure, similar to components in ...
Cryo-electron tomography, or cryo-ET for short, can be used to visualize and analyze cellular structures in their natural environment. Researchers at the Max Planck Institute of Biochemistry (MPIB) in ...
A team of researchers at Roswell Park Comprehensive Cancer Center, led by Dhyan Chandra, Ph.D., has discovered a new therapeutic target for neuroendocrine prostate cancer, a rare and hard-to-treat ...
HOUSTON (Jan. 21, 2010) – In proper society of yesterday, the chaperone insured that couples maintained proper courting rituals. In biology, a group of proteins called chaperonins makes sure that ...
