BacterialSortase Substrate III, Abz/DNP TFA是一种用于检测金黄色葡萄球菌转肽酶分选酶A (SrtA) 活性的内部淬灭荧光肽底物。当SrtA与此底物反应时,会催化苏氨酸的羧基与细胞壁交联桥的氨基形成酰胺键,并导致该底物在Ex/Em=320 nm/420 nm下被裂解,可以通过该波长检测其裂解情况。

产品描述 | Bacterial Sortase Substrate III, Abz/DNP TFA is an internally quenched fluorescent peptide used to monitor the activity of the Staphylococcus aureus transpeptidase sortase A (SrtA). This enzyme catalyzes the formation of an amide bond between the carboxyl group of threonine and the amino group of cell-wall crossbridges by cleaving its native substrate, Bacterial Sortase Substrate III, Abz/DNP. The cleavage event can be detected with excitation/emission wavelengths of Ex/Em=320 nm/420 nm. |
