chaperonin /chap·er·o·nin/ (shap″er-o´nin) any of various heat shock proteins that act as molecular chaperones in bacteria, plasmids, mitochondria, and eukaryotic cyotsol.
Chaperonin Any of a group of 60 kD cytosolic chaperone proteins—e.g., heat shock protein 60, hsp60, GroEL—found in prokaryotes, the equivalent of the eukaryotic hsp60, mitochondria and plastids; chaparonins use energy from ATP hydrolysis to maintain proteins in the necessary folded configuration for proper function, thus having ‘foldase’ activity; other postulated roles for chaperonins include protein transport, oligomer assembly, DNA replication, mRNA turnover, and protection of the cell from various stresses; some chaperonins have auto-foldase activities
