MALT1casp‐Ig3 (mucosa‐associated lymphoid tissue lymphoma translocation protein 1) in complex with the tricyclic phenothiazine derivative thioridazine (violet in the picture), the inhibitor is bound in a hydrophobic pocket far from the active site. This explains the action of phenothiazine derivatives as noncompetitive, reversible inhibitors.
第二个位点:在人类MALT1 casp-Ig3(与粘膜相关的淋巴组织淋巴瘤易位蛋白1)的晶体结构中,与三环吩噻嗪衍生物硫代哒嗪(图中的紫罗兰)形成复合物,该抑制剂结合在远离水的疏水口袋中。活动站点。这解释了吩噻嗪衍生物作为非竞争性可逆抑制剂的作用。
