					<description><![CDATA[<p>GroEL-GroES is a bacterial Hsp60 chaperonin system that assists protein folding through an ATP-dependent cycle. Discover how GroEL captures non-native proteins, GroES forms the folding chamber, and repeated cycles promote productive protein folding while limiting aggregation.</p>
