甲状腺受体信号调控重要生理过程,信号紊乱可引发癌症、代谢和神经疾病等严重健康问题,因此检测甲状腺受体配体具有重要毒理学和药理学意义。作者此前报道了利用无细胞蛋白合成表达由人甲状腺受体β(hTRβ)激活域与β-内酰胺酶报告域组成的嵌合融合蛋白,用于检测甲状腺受体配体。本研究通过重新设计该嵌合融合蛋白生物传感器,将报告系统替换为全长β-...

全细胞生物传感器可用于抗菌药物发现,原则上可识别作用于特定高价值通路的抑制剂。已有多种细胞壁合成抑制剂(CWBIs)生物传感器,但特异性或敏感性不足,且大多未作为初筛工具严格评估。本文构建并验证了多种金黄色葡萄球菌 CWBI 生物传感器,证明其可特异、灵敏地发现 CWBIs。传感器由金黄色葡萄球菌启动子(PgltB、PilvD、Pm...
