具有亲电官能团的植物源天然产物(NP)通过亲核半胱氨酸残基的共价修饰接合蛋白质组的各种子集。这种亲电-亲核相互作用可以改变蛋白质的构象,改变蛋白质的功能,并调节它们的生物学作用。这些共价蛋白质修饰在健康和疾病中的生物学意义已经越来越被认识到。理解共价NP-蛋白质相互作用的一种方法是利用传统的蛋白质组学和基于现代质谱(MS)的蛋白质组学策略。这些策略已被证明在发现特定NP蛋白靶点方面是有效的,并且是关键的第一步,其允许更深入地理解NP调节细胞过程的能力。在这里,我们回顾了植物来源的NP共价修饰蛋白质,这些共价修饰的生物学意义,以及不同的蛋白质组学策略,已被用来研究这些NP-蛋白质相互作用。
Plant-derived natural products (NPs) with electrophilic functional groups engage various subsets of the proteome via covalent modification of nucleophilic cysteine residues. This electrophile-nucleophile interaction can change protein conformation, alter protein function, and modulate their biological action. The biological significance of these covalent protein modifications in health and disease has been increasingly recognized. One way to understand covalent NP-protein interactions is to utilize traditional proteomics and modern mass spectrometry (MS)-based proteomic strategies. These strategies have proven effective in uncovering specific NP protein targets and are critical first steps that allow for a much deeper understanding of the ability of NPs to modulate cellular processes. Here, we review plant-derived NPs that covalently modify proteins, the biological significance of these covalent modifications, and the different proteomic strategies that have been employed to study these NP-protein interactions.
