Two fluorescent lysine amide analogs, in which the carboxyl end of lysine was covalently attached to dansyl or NBD groups through an ethylene glycol-based linker, were rationally designed and synthesized. Both probes showed high binding affinity to the lysine riboswitch in vitro and their fluorescence intensities decreased by riboswitch binding.
合成了两种荧光赖氨酸酰胺类化合物,其中赖氨酸的羧基末端通过一种基于乙二醇的联接剂与丹色(dansyl)或NBD基团共价连接。这两种探针在体外对赖氨酸核糖开关表现出较高的结合亲和力,并且它们的荧光强度因核糖开关结合而降低。
