Chaperone protein. Molecular models of the GroEL-GroES complex chaperone protein from the bacterium Escherichia coli. It is composed of two stacked rings of seven GroEl proteins that form a central cavity and a GroES cap on one end. The cavity provides an enclosed environment for cellular proteins to fold themselves into their final structure. Misfolded proteins can form harmful aggregations within cells.
