GroEL and GroES are essential molecular chaperones found in bacteria, helping proteins fold correctly. GroEL is a cylindrical structure that provides a protective environment for misfolded proteins, while GroES acts as a lid that seals the chamber during the folding process. Together, they facilitate the proper assembly of proteins by preventing aggregation and ensuring that they achieve their functional conformations. This process is crucial for cellular health, as correctly folded proteins are necessary for various biological functions and processes within the cell.
