Different conformations of the catalytic loop and Arg400. Structural superimposition of MDCC–Hsp90αMC (magenta), the protomer in the E. coli Hsp90/HTPG open-state dimer (without ATP binding, yellow; PDB entry 2ioq) and the protomer in the human Hsp90α closed-state dimer (with ATP analog bound, gray; PDB entry 7l7j). The inset details the various conformations of the catalytic loop and Arg400. MDCC and Arg400 are shown in stick representation. |
