蛋白质快速氧化(FPOP)是一种羟基自由基蛋白质足迹(HRPF)方法,用于研究蛋白质结构,蛋白质-配体相互作用和蛋白质-蛋白质相互作用。FPOP利用248 nm的KrF准分子激光器光解过氧化氢以产生羟基自由基,羟基自由基进而氧化修饰溶剂可接近的氨基酸侧链。最近,我们扩大了FPOP在秀丽隐杆线虫体内氧化标记中的应用。elegans),标题为IV-FP 0 P。透明线虫已被用作许多人类疾病的模型系统。结构研究C.通过IV-FPOP修饰秀丽隐杆线虫是可行的,因为动物摄取过氧化氢的能力,它们对248 nm激光照射的透明性,以及修饰的不可逆性。本文描述了用于IV-FPOP标记、IV-FPOP参数、蛋白质提取和LC-MS/MS优化参数的微流体流动系统的组装。
Fast oxidation of proteins (FPOP) is a hydroxyl radical protein footprinting (HRPF) method used to study protein structure, protein-ligand interactions, and protein-protein interactions. FPOP utilizes a KrF excimer laser at 248 nm for photolysis of hydrogen peroxide to generate hydroxyl radicals which in turn oxidatively modify solvent-accessible amino acid side chains. Recently, we expanded the use of FPOP of in vivo oxidative labeling in Caenorhabditis elegans (C. elegans), entitled IV-FPOP. The transparent nematodes have been used as model systems for many human diseases. Structural studies in C. elegans by IV-FPOP is feasible because of the animal’s ability to uptake hydrogen peroxide, their transparency to laser irradiation at 248 nm, and the irreversible nature of the modification. The assembly of a microfluidic flow system for IV-FPOP labeling, IV-FPOP parameters, protein extraction, and LC-MS/MS optimized parameters are described herein.
