This invention concerns an enzyme substrate consisting of a target part and a marker part, hydrolysis of the substrate leading to separation of the target part from the marker part, and said target part being specific for the enzyme activity being assayed. It also concerns a formulation containing at least one such substrate, and a method for detecting the bacterial species
Pseudomonas aeruginosa.
The target part of the substrate is specific for &bgr;-alanine aminopeptidase activity and the marker part is a compound which reveals whether a hydrolysis reaction has taken place or not.
The invention is particularly applicable in the field of diagnosis.
本发明涉及一种酶底物,包括目标部分和标记部分,水解该底物导致目标部分与标记部分分离,且所述目标部分特异于正在检测的酶活性。本发明还涉及至少含有这样的底物的配方,以及一种检测细菌种Pseudomonas aeruginosa的方法。该底物的目标部分特异于β-丙氨酸氨肽酶活性,标记部分是一种化合物,用于显示是否发生了水解反应。本发明特别适用于诊断领域。
