一氧化氮作为氧载体和氧代谢金属酶中氧结合位点的电子顺磁共振探针已经使用了20多年。NO与氧和超氧阴离子的高反应性及其对金属蛋白的高亲和力使生物化学家认为NO是对活细胞具有高毒性的化合物。这一论断最近在一些具有重大意义的发现之后被重新考虑:发现了NO激活鸟苷酸环化酶,认识到NO是内毒素和炎症激活巨噬细胞时释放的亚硝酸根和硝酸根离子的前体,证明NO是内皮源性松弛因子,以及发现NO从L-精氨酸生物合成,一种在各种生物细胞间信号传导过程中常见的途径。目前认为,NO在哺乳动物细胞内、不同类型细胞之间以及宿主防御反应中起着关键的生物调节作用。在本综述中,我们试图给出一个一般的图片是什么已知的化学,物理,生物化学和生物物理性质的NO之间的各种氮氧化物。我们已经集中在结构信息,可以通过电子顺磁共振光谱的亚硝基金属蛋白复合物。最后,我们已经表明如何分子目标的一氧化氮可以表征,在整个细胞内,通过电子顺磁共振光谱。
Nitric oxide has been used for more than 20 years as an electron paramagnetic resonance probe of oxygen binding sites in oxygen-carriers and oxygen-metabolizing metalloenzymes. The high reactivity of NO with oxygen and the superoxide anion and its high affinity for metalloproteins led biochemists to consider NO as a highly toxic compound for a living cell. This assertion has recently been reconsidered following a number of discoveries of great significance: the finding of the activation of guanylate cyclase by NO, the recognition that NO is the precursor of nitrite and nitrate ions released in the activation of macrophages by endotoxin and cytokities, evidence that NO is an Endothelium-Derived Relaxing Factor, and the discovery of NO-biosynthesis from l-arginine, a pathway common in various biological cell-to-cell signalling processes. It is now admitted that NO plays a key bioregulatory role within mammalian cells, between cells of different types and in the host defence response. In the present review we have attempted to give a general picture of what is known of the chemical, physical, biochemical and biophysical properties of NO among the various nitrogen oxides. We have focussed on the structural information that can be obtained by electron paramagnetic resonance spectroscopy of nitrosyl-metalloprotein complexes. Finally we have shown how molecular targets of nitric oxide can be characterized, within whole cells, by electron paramagnetic resonance spectroscopy.
