核糖开关是假定的药物靶点,因为它们经常调节必需细菌基因的表达。这一发现需要开发合适的检测方法,在最好的高通量(HT)兼容的情况下,允许筛选核糖开关激活的化合物库。在这里,我们描述了一种ht兼容的基于荧光的筛选实验,采用枯草芽孢杆菌glmS核酶的最小核心基序和代谢物诱导的自裂解实验,使用金黄色葡萄球菌的全长glmS核酶来鉴定激活这种调节RNA的人工分子。
Ribsowitches are putative drug targets as they often regulate the expression of essential bacterial genes. This finding necessitates the development of suitable assays, at best high-throughput (HT) compatible, which allow the screening of compound libraries for riboswitch activation. Here, we describe a HT-compatible fluorescence-based screening assay employing a minimal core motif of theBacillus subtilisglmS riboswitch and the metabolite-induced self-cleavage assay using the full-length glmS ribozyme ofStaphylococcus aureusfor the identification of artificial molecules activating this regulatory RNA.
