In order to mimic this repair process of apoenzyme, we synthesized two model compounds, in which tryptophan and/or tyrosine was covalently linked to cyclobutane thymine dimer, and measured the splitting quantum yield of dimer under 295 nm light. By investigating the photosensitized splitting properties of the dimer, some new insights into the intramolecular electron-transfer process were gained.

为了模拟酶蛋白的这一修复过程，合成了色氨酸和/或酪氨酸与胸腺嘧啶二聚体共价连接的化合物，作为酶-底物复合物的模型，研究了它们在295 nm光照射下氨基酸残基光敏化二聚体裂解的性质，测定了二聚体裂解量子产率，获得一些新的结果并对其进行了分析。

Its chemical structure is similar with glutamate, one of the typical excitatory amino acids .

喹啉酸是体内色氨酸的代谢产物，其化学结构与谷氨酸类似，在中枢神经系统能够激活谷氨酸能神经的N-甲基-D天冬氨酸受体，造成神经兴奋毒作用。

For the protein side chain,the band at 1 368 cm-1 assigned to the "buried" tryptophan shifted to 1 365 cm-1 of the "exposed" and the relative intensity reduced 59%. The relative intensity of 635 cm-1 assigned to the gauche conformation of the C—S decrased 15% and the band at 725 cm-1 increased 58%.These indicate that the structure of the protein changed in the diabetic serum.The relative intensity at 1 449 cm-1 assigned to the lipids characteristic increased 58%.The relative intensity of the glucide characteristic at 1 331,1 099 and 740 cm-1 increased 35%,100% and 62%,respectively.

蛋白质侧链色氨酸吲哚环&埋藏式&的谱线1 368 cm-1位移到&暴露式&的1 365 cm-1，且相对强度减少了59%；侧链C—S键的扭曲构象的谱线635 cm-1相对强度减少了15%，而反式构象的谱线725 cm-1增加了58%，说明C—S键的扭曲构象部分转变为反式构象，表明糖尿病人血清中蛋白质的有序结构发生变化；类脂物特征峰1 449 cm-1相对强度增加了58%，与糖类有关的特征峰谱线1 331，1 099和740 cm-1相对强度分别增加了35%，100％和62%，从而表明糖尿病人血清中与脂类和糖蛋白有关的物质含量增加。

The enzyme amplified lanthanide luminescent spectrometry of horseradish peroxidase was developed and applied to the analyse of HRP and tuberculosis. The deconvolution curve method was used for synchronous fluorimetric determination of two component systems of highly overlapped spectra, such as phenol and p-dihydroxybenzene, phenol and o-dihydroxybenzene, and tyrosine and tryptophan. A novel mathematical method, combining Gorry's deconvolution method, was presented to remedy data loosing of SavitzkyGolay's deconvolution method and applied to dealing with fluorescent signal.
