    • An inventive substrate is provided which includes a substrate compound of formula A-B1-B2-B3-B4: wherein A is a sugar moiety; B1 is a linker moiety allowing the conjugation of moiety A and the remaining structure of the substrate; B2 is a linker moiety with a free reactive amino group so as to be available for reaction with carboxylic acids or detectable tags; B3 contains a permanently charged element such as a quaternary ammonium group so as to increase sensitivity for mass spectrometry analysis; and B4 of various carbon length conferring specificity amongst individual substrates in detection methods. Also provided is a molecule of the formula B1-B2-B3-B4, with similar structural characteristics to an enzymatic product produced by the action of a target enzyme on an inventive substrate. Further provided are methods for using inventive substrates for detecting enzymatic activity.
    • 提供了本发明的底物,其包括式A-B1-B2-B3-B4的底物化合物:其中A是糖部分; B1是连接部分,允许部分A与底物的剩余结构共轭; B2是具有游离反应性氨基的接头部分,以便可用于与羧酸或可检测标签反应; B3含有永久带电元件如季铵基,以提高质谱分析的灵敏度; 和各种碳长度的B4在检测方法中在各个底物之间赋予特异性。 还提供了式B1-B2-B3-B4的分子,其与通过靶酶在本发明底物上的作用产生的酶产物具有相似的结构特征。 还提供了使用本发明的底物检测酶活性的方法。
