  • The discovery of chaperonins means that a general, works-for-every-protein folding solution may still not be possible.

  • GroEL, a member of a large family of chaperonins, works in concert with GroES to encapsulate a substrate protein, isolating it as it folds.

  • Further studies using this new method may help to determine whether the failure of chaperonins is responsible for pathogenic aggregation, clumping of protein, that leads to disease.

  • Until now, the slow speed of manual mixing prevented single-molecule measurements of folding inside chaperonins at times earlier than a few minutes.

  • The way in which these chaperonins complete a large mechanical motion critical for completing a protein-folding event is different from that of others that have been studied.

  • In a new study in archaea (single-celled organisms without nuclei to enclose their genetic information), a consortium of researchers from Baylor College of Medicine and Stanford University in California discovered how the Group II chaperonins close and open folding chambers to initate the folding event and to release the functional protein to the cell.

  • "Previously, people had studied chaperonins in the bacteria Escherichia coli," said Chiu, also director of the National Center for Macromolecular Imaging and of the Nanomedicine Development Center at BCM.
