基于活性的蛋白质谱分析(Activity-based protein profiling,ABPP)是一种靶向功能蛋白质组学方法,它利用小分子探针与蛋白质类的活性位点发生共价反应来显示活性蛋白质组。比较两种不同样品的活性谱并不总是容易的,特别是当使用产生太多信号的探针时。为了准确比较两个蛋白质组之间的蛋白质活性,我们开发了差异凝胶电泳ABPP(DIGE-ABPP),它比较了同一凝胶泳道中两个荧光标记的蛋白质组。该协议描述了两个蛋白质组的标记与炔标记的探针,然后通过耦合与两个不同的荧光团使用“点击化学”,分离蛋白质凝胶上的混合蛋白质组,和定量和比较的活动概况。利用DIGE-ABPP技术研究了本氏烟草(Nicotiana benthamian)在番茄假单胞菌(Pseudomonasep.v.tomatoDC3000)诱导下质外体中丝氨酸水解酶活性的变化。
Activity-based protein profiling (ABPP) is a targeted functional proteomics method that displays the active proteome by using small molecule probes that react covalently with the active sites of protein classes. Comparison of activity profiles from two different samples is not always easy, especially when using probes that generate too many signals. For accurate comparison of protein activities between two proteomes, we developed difference gel electrophoresis ABPP (DIGE-ABPP), which compares two fluorescently labeled proteomes in the same gel lane. This protocol describes the labeling of two proteomes with alkyne-labeled probes, followed by the coupling with two different fluorophores using “click chemistry,” the separation of mixed proteomes on protein gels, and the quantification and comparison of the activity profiles. We applied DIGE-ABPP to investigate differential serine hydrolases activities in the apoplast ofNicotiana benthamianachallenged withPseudomonas syringaep.v.tomatoDC3000.
