红外光谱长期以来一直被用于检查膜蛋白的平均二级结构和取向。随着最近利用位点特异性同位素标记(例如,肽1- 13 C = 18 O),现在可以检查局部性质,而不是全局平均值。位点特异性红外二色性(SSID)技术利用了这一事实,并推导出标记的氨基酸的位点特异性取向限制。这些限制可以用来解决简单的α-螺旋束的骨架结构,强调这种方法的能力。到目前为止,SSID已经在衰减全内反射光学模式下进行,具有衰减全内反射的所有相应注意事项。在本报告中,我们通过使用透射红外光谱倾斜系列扩展了SSID。我们开发了相应的理论,并证明了准确的特定网站的取向限制,可以从一个简单的传输实验。
Infrared spectroscopy has long been used to examine the average secondary structure and orientation of membrane proteins. With the recent utilization of site-specific isotope labeling (e.g., peptidic 1–13C=18O) it is now possible to examine localized properties, rather than global averages. The technique of site-specific infrared dichroism (SSID) capitalized on this fact, and derives site-specific orientational restraints for the labeled amino acids. These restraints can then be used to solve the backbone structure of simpleα-helical bundles, emphasizing the capabilities of this approach. So far SSID has been carried out in attenuated total internal reflection optical mode, with all of the respective caveats of attenuated total internal reflection. In this report we extend SSID through the use of transmission infrared spectroscopy tilt series. We develop the corresponding theory and demonstrate that accurate site-specific orientational restraints can be derived from a simple transmission experiment.
