AMP-PCP disodium是一种ATP类似物,可以以Kd值为3.8μM来结合到Hsp90的N末端结构域;AMP-PCP disodium结合有利于Hsp90活性同型二聚体的形成;AMP-PCP binding favors the formation of the active homodimer of Hsp90 by enhancing the slow-motion featured conformational exchanges of those residues (A117-A141) within the lid segment (A111-G135) and around region;In total, 170 non-proline residues are identified for the triple-labeled Hsp90 bound with AMP-PCP
