蛋白质快速光化学氧化(FPOP)是一种羟基自由基蛋白质足迹法,通过过氧化氢的光解共价标记溶剂可接近的氨基酸。最近,我们扩大了使用FPOP在体内(IV-FPOP)共价标记C。优美的在最初的IV-FPOP研究中,545种蛋白质在蠕虫体内的所有身体系统中被氧化修饰。在这里,通过使用化学渗透增强剂(CPE),我们增加了修饰蛋白的数量以及每个蛋白质的修饰数量,以获得更多的结构信息。CPE有助于过氧化氢在C内的输送。通过扰乱蠕虫表皮的高度有序的脂质双层而不影响蠕虫的生存能力。使用CPE azone进行的IV-FPOP实验显示氧化修饰的蛋白质和肽增加。这种增加与C.使用化学荧光团定量的线虫,证明了使用CPE与IV-FPOP的功效。质谱蛋白质组学数据可通过ProteomeXchange获得,标识符为PXD 019290。
Fast photochemical oxidation of proteins (FPOP) is a hydroxyl radical protein footprinting method that covalently labels solvent-accessible amino acids by photolysis of hydrogen peroxide. Recently, we expanded the use of FPOP for in vivo (IV-FPOP) covalent labeling in C. elegans. In initial IV-FPOP studies, 545 proteins were oxidatively modified in all body systems within the worm. Here, with the use of chemical penetration enhancers (CPEs), we increased the number of modified proteins as well as the number of modifications per protein to gain more structural information. CPEs aid in the delivery of hydrogen peroxide inside C. elegans by disturbing the highly ordered lipid bilayer of the worm cuticle without affecting worm viability. IV-FPOP experiments performed using the CPE azone showed an increase in oxidatively modified proteins and peptides. This increase correlated with greater hydrogen peroxide uptake by C. elegans quantified using a chemical fluorophore demonstrating the efficacy of using CPEs with IV-FPOP. Mass spectrometry proteomics data are available via ProteomeXchange with identifier PXD019290.
