摘要

摘要利用纳米银颗粒记录和分析了猪肾中 D-氨基酸氧化酶的表面增强拉曼散射光谱，揭示了 D-氨基酸激活该酶过程中黄素腺嘌呤二核苷酸辅因子构象变化的特征光谱参数。研究发现，记录黄素腺嘌呤二核苷酸构象变化的时间取决于酶的底物特异性：在 D-丙氨酸存在的情况下，需要几秒钟，而在 D-丝氨酸存在的情况下，需要几分钟。

A Raman Spectroscopic Study of the Conformation of Flavin Adenine Dinucleotide, a CoEnzyme of D-Amino Acid Oxidase

The spectra of surface-enhanced Raman scattering of D-amino acid oxidase from pig kidney were recorded and analyzed using silver nanoparticles; characteristic spectral parameters of changes in the conformation of the flavinadenine dinucleotide cofactor during activation of the enzyme by D-amino acids were revealed. It was found that the time during which changes in the conformation of the flavinadenine dinucleotide were recorded depended on the substrate specificity of the enzyme: in the presence of D-alanine, this took several seconds, and in the presence of D-serine, minutes.
