Crystal Structure of the Chaperonin Complex Cpn60/Cpn10/(ADP)7 from Thermus Thermophilus

Overview

The chaperonins GroEL and GroES are essential mediators of protein folding. GroEL binds nonnative protein, ATP, and GroES, generating a ternary complex in which protein folding occurs within the cavity capped by GroES (cis-cavity). We determined the crystal structure of the native GroEL-GroES-ADP homolog from Thermus thermophilus, with substrate proteins in the cis-cavity, at 2.8 A resolution. Twenty-four in vivo substrate proteins within the cis-cavity were identified from the crystals. The structure around the cis-cavity, which encapsulates substrate proteins, shows significant differences from that observed for the substrate-free Escherichia coli GroEL-GroES complex. The apical domain around the cis-cavity of the Thermus GroEL-GroES complex exhibits a large deviation from the 7-fold symmetry. As a result, the GroEL-GroES interface differs considerably from the previously reported E. coli GroEL-GroES complex, including a previously unknown contact between GroEL and GroES.
