    • A method for detecting transferase activity of a sample includes contacting the sample with a substrate and at least one of a phosphate group donor and a phosphate group acceptor. The substrate includes a reporter compound and amino acids. A peptidase is added that cleaves a non-phosphorylated substrate at a first rate and a phosphorylated substrate and a second rate. The output of the reporter compound is detected. In a preferred embodiment, the transferase activity detected is a kinase activity. In another preferred embodiment, the transferase activity detected is a phosphatase activity. Also provided is a method of screening for alterations in a transferase reaction. Kits and peptide substrate are also provided for carrying out at least one of the methods of the invention.
    • 用于检测样品的转移酶活性的方法包括使样品与底物和磷酸基供体和磷酸酯基受体中的至少一种接触。 底物包括报告化合物和氨基酸。 加入肽酶,其以第一速率和磷酸化底物和第二速率切割非磷酸化底物。 检测报告化合物的输出。 在优选的实施方案中,所检测的转移酶活性是激酶活性。 在另一个优选的实施方案中,所检测的转移酶活性是磷酸酶活性。 还提供了筛选转移酶反应中的改变的方法。 还提供了用于实施本发明的至少一种方法的试剂盒和肽底物。
