当前结构生物学的努力旨在将结构信息整合到细胞组织和功能的背景下。 X 射线和红外辐射位于电磁波谱的两端,可作为实现这一目标的互补探针。强而明亮的光束由同步加速器辐射产生,并有效地用于从硬 X 射线延伸到远红外(或太赫兹)范围的波长域。 X 射线晶体学提供了原子结构的精致细节,而傅里叶变换红外显微光谱 (FTIRM) 正在成为一种光谱探针和成像工具,用于将分子结构与生化动力学和功能相关联。在本手稿中,根据最近的成就讨论了同步加速器 FTIRM 在弥合“功能生物学”差距方面的作用,并对生物学和生物医学研究的贡献进行了批判性评估。
Current efforts in structural biology aim to integrate structural information within the context of cellular organization and function. X-rays and infrared radiation stand at opposite ends of the electromagnetic spectrum and act as complementary probes for achieving this goal. Intense and bright beams are produced by synchrotron radiation, and are efficiently used in the wavelength domain extending from hard X-rays to the far-infrared (or THz) regime. While X-ray crystallography provides exquisite details on atomic structure, Fourier transform infrared microspectroscopy (FTIRM) is emerging as a spectroscopic probe and imaging tool for correlating molecular structure to biochemical dynamics and function. In this manuscript, the role of synchrotron FTIRM in bridging the gap towards ‘functional biology’ is discussed based upon recent achievements, with a critical assessment of the contributions to biological and biomedical research.
