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。
