Allosteric interactions: Metal(II) cyclens inhibit Ras-effector interactions by stabilizing a weak effector-binding state of Ras, state 1(T), and binding directly in the active site. The novel state (1T) inhibitor Zn(2+)-BPA (BPA = bis(2-picolyl)amine) binds outside the nucleotide binding pocket but nevertheless allosterically stabilizes state 1(T) and thus inhibits the Ras-Raf interaction.
金属(II) 环笼通过稳定 Ras 效应物结合较弱的 Ras 状态(状态 1(T))来抑制 Ras 效应物相互作用,并直接结合在活性位点。新型的状态 1(T)抑制剂 Zn(2+)-BPA(BPA = 双(2-吡啶基)胺)结合在核苷酸结合口袋之外,但仍然变构稳定状态 1(T),从而抑制 Ras-Raf 相互作用。
