Study on the interaction of me2sncl2 with apo - ovotransferrin by uv difference spectra 2与脱铁伴清蛋白作用的紫外差光谱研究
The temperature induction expression of the recombinant e . coli . was carried out and vhb protein of 16k - d was expressed . 3 we demonstrated the vhb owns biological activity by co difference spectrum ) 2构建了含有vgbm基因的原核表达载体pbv221svhb并转化大肠杆菌菌株bl21 ,经热激诱导,在培养物中检测到了约16kd具有生物活性的vhb蛋白。
Absorption , fluorescence emission and excitation spectra of five pigment - protein complexes were determined . photosynthetic electron transfer was measured from the dcip photoreduction . p700 concentration was assayed from the ferricyanide - oxdised minus ascorbate - reduced difference spectrum 测定裙带菜各色素蛋白复合物的吸收光谱、荧光发射光谱和荧光激发光谱,并进行了dcip的光还原测定和化学法的氧化还原差示光谱测定。
By observing the effect of acidity on the uv difference spectra of ehpg or hbed , the spectral characteristics of apoovotransferrin binding to metals and anions at ph 7 . 4 show that the reaction of apoovotransferrin with metals is related to deprotonation of the phenolic group of tyrosine of the metal binding sites , while the binding of apoovotransferrin to anions is associated with the protonation of the phenolic group of tyrosine of the anion binding sites 摘要通过观察酸度对模拟转铁蛋白小分子ehpg和hbed紫外差光谱的影响,结合脱铁伴清蛋白与金属离子、阴离子结合的光谱特性,推断脱铁伴清蛋白与金属离子的结合导致金属离子结合位点处酪氨酸酚羟基的去质子化,而与阴离子的结合导致阴离子结合位点处酪氨酸酚羟基的质子化。
