The structures of GroEL single subunit in P, M and open states. A. The distance map of GroEL single subunit (4HEL_A). The cutoff distance is 30 Å. B–D. The conformations of M (B), P (C) and open (D) states. These structures are retrieved from Protein Data Bank (PDB) [16]. PDB IDs of M, P and open states are 4HEL_A, 1KP8_A and 1AON_A, respectively. Equatorial domain is colored in red, intermediate domain in green, arm domain in magenta, and head domain in cyan. The grey molecule in P state is an ATP analogue. The grey molecule in D is ADP. In P state, three residues mutated for crystallization are shown in yellow space-filling model. Images of the structures were drawn with PyMOL [26].
