Porphobilinogen synthase (PBGS) catalyzes the first common step in the biosynthesis of the essential heme, chlorophyll and vitamin B(12) heme pigments. PBGS activity is regulated by assembly state, with certain oligomers exhibiting biological activity and others either partially or completely inactive, affording an innovative means of allosteric drug action. Pseudomonas aeruginosa PBGS is functionally
胆色素原合酶 (PBGS) 催化基本血红素、叶绿素和维生素 B(12) 血红素色素生物合成的第一个常见步骤。PBGS 活性受组装状态调节,某些低聚物表现出生物活性,而其他低聚物部分或完全无活性,提供了一种变构药物作用的创新方法。铜绿假单胞菌 PBGS 作为八聚体具有功能活性,作为二聚体无活性。我们已经通过计算预筛选和本机 PAGE 凝胶迁移率变化分析确定了一系列稳定非活性铜绿假单胞菌二聚体的化合物。根据这些结果,我们制备了相关的噻二唑并评估了它们调节铜绿假单胞菌 PBGS 组装状态的能力。
