NodD binds to and bends target promoters through anchoring two tandem and individual specific DNA sites. NodD functions as a tetramer, which has a V-shaped main body. Tetrameric NodD is to change its own conformation rather than its oligomeric forms in response to small signal molecules. The specific interaction between each NodD DNA-binding domain and each specific DNA site does not alter itself in spite of naringenin induction, and the induced conformational change is transferred from protein to DNA. Only the DNA conformation incited by induced NodD is competent for RNA polymerase to form the transcriptional open complex. It cannot be excluded that NodD may have protein-to-protein contacts with RNA polymerase, and that the NodD conformational change may also directly contribute to the transcriptional open complex formation. However, the NodD conformational change itself cannot serve as the determinant of the transcriptional molecular switch.
通过研究,我们提出了初步的NodD操纵子激活模型:第一,四聚体是NodD蛋白的功能单位,它通过铆钉两个串联的相对独立的DNA靶位点结合被诱导的启动子;第二,小分子配基的结合是改变NodD四聚体的构象而不是引发不同形式的寡聚体,在我们的模型中,NodD四聚体缩小其V形主体的弯折角,进而缩短其DNA结合功能域的间距;第三,小分子信号的诱导并没有改变NodD的DNA结合域和其DNA靶位点的相互作用,NodD的构象改变由蛋白质经其双铆钉位点传递给DNA;第四,只有诱导状态的NodD激发的DNA构象才能有效地使RNA聚合酶形成转录开放复合物;第五,不排除NodD与RNA聚合酶可能有直接的相互接触位点,不排除NodD构象的改变可能直接有利于RNA聚合酶形成转录开放复合物,但是我们认为NodD构象改变本身不是充当转录激活开关的决定因素。

POMs and deys are still maintained integrallty.AFM exhibits the films is even.The thickness of each layer is about 1.25nm. The AFM images reflect that there are some protuberances on the outer surface layer of the film, which due to the aggregates of spherical structure PMo12. Cyclic Voltammograms reflects the redox potentials of dye in multilayer shifts towards more positive values than pure dye multiplayer which may be explained by charge transfer from dye to POM. Fluorescence spectra show that polyoxometalates caused the fluorescence decay of dyes, which maybe used as fluorescence sensors.
UV-VIS说明复合膜均匀生长; IR 光谱、XPS能谱研究结果表明,紫外光照前后,膜中多酸/染料分子间没有发生显著的光化学反应,各组分的结构仍然保持;原子力显微镜显示,膜的外表面是均匀的,每一个双层厚度大约是1.25nm,膜表面的隆起,可能是多酸阴离子簇堆积所引起;循环伏安测定结果表明,由于多酸阴离子的影响,有机染料的氧化还电位发生了正的偏移,反映出复合膜中染料分子与多酸阴离子间发生了荷移相互作用,导致染料分子失去部分电子而使氧化性略强;荧光光谱研究结果表明,多酸阴离子可以有效地引发荧光染料的荧光淬灭,这为多酸在荧光传感器方面的应用提供了有价值的信息。
