    通过电荷反转衍生提高类二十烷酸的灵敏度质谱检测
    摘要:
    液相色谱-电喷雾电离-串联质谱联用 (LC-ESI-MS/MS) 是一种分析多不饱和脂肪酸(包括类二十烷酸)含氧代谢物的强大方法。这里我们描述了一种新的衍生化试剂N的合成-(4-氨基甲基苯基)吡啶鎓 (AMPP),可通过酰胺键以定量产率与类二十烷酸偶联。与未衍生化分析物的负模式电喷雾电离检测相比,将类二十烷酸的羧酸转化为阳离子 AMPP 酰胺可将检测灵敏度提高 10 到 20 倍。这种电荷反转衍生允许在电喷雾电离质谱仪中检测阳离子而不是阴离子,从而提高灵敏度。另一个因素是 AMPP 酰胺在分析物部分而不是仅在阳离子标签部分发生相当大的碰撞诱导解离,这使得同量异位衍生物可以通过串联质谱法进行区分,这进一步提高了灵敏度和特异性。这种简单的衍生方法允许前列腺素,2、白三烯B 4、羟基二十碳四烯酸异构体和花生四烯酸在复杂生物样品中定量,定量限在200-900 fg范围内。可以预期,AMPP 衍生化

  • Crystal Structure of a Lipoxygenase in Complex with Substrate

    Background: Lipoxygenases (LOX) catalyze the oxygenation of polyunsaturated fatty acids but generate distinct products from a common substrate. Results: We report the first structure of a LOX-substrate complex. Conclusion: The structure provides a context for understanding product specificity in enzymes that metabolize arachidonic acid. Significance: With roles in the production of potent lipid mediators, LOX are targets for drug design.Lipoxygenases (LOX) play critical roles in mammalian biology in the generation of potent lipid mediators of the inflammatory response; consequently, they are targets for the development of isoform-specific inhibitors. The regio- and stereo-specificity of the oxygenation of polyunsaturated fatty acids by the enzymes is understood in terms of the chemistry, but structural observation of the enzyme-substrate interactions is lacking. Although several LOX crystal structures are available, heretofore the rapid oxygenation of bound substrate has precluded capture of the enzyme-substrate complex, leaving a gap between chemical and structural insights. In this report, we describe the 2.0 angstrom resolution structure of 8R-LOX in complex with arachidonic acid obtained under anaerobic conditions. Subtle rearrangements, primarily in the side chains of three amino acids, allow binding of arachidonic acid in a catalytically competent conformation. Accompanying experimental work supports a model in which both substrate tethering and cavity depth contribute to positioning the appropriate carbon at the catalytic machinery.
