变构蛋白在“非活性”和“活性”状态之间转换。一般来说,这类蛋白质在二级、三级和/或四级结构水平上呈现出不同的构象状态。变构蛋白的不同构象可以是抗原性不同的,并诱导具有高度独特的特异性和中和功能作用的抗体。在这里,我们总结了针对甘露糖特异的细菌粘附素FimH的不同变构构象的不同功能类型的单抗的研究。粘附素FimH是大肠杆菌和其他肠道细菌最常见的细胞附着蛋白。包括通过与配体诱导的结合部位相互作用或通过嵌在结构域之间激活FimH功能的抗体类型,以及通过正位、副星形或新的动力机制抑制FimH的抗体。了解抗体对变构蛋白作用的分子机制有助于深入了解如何设计具有预期功能效果的抗体,包括那些对细菌和病毒细胞附着蛋白具有中和活性的抗体。
Allosteric proteins transition between ‘inactive’ and ‘active’ states. In general, such proteins assume distinct conformational states at the level of secondary, tertiary and/or quaternary structure. Different conformers of an allosteric protein can be antigenically dissimilar and induce antibodies with a highly distinctive specificities and neutralizing functional effects. Here we summarize studies on various functional types of monoclonal antibodies obtained against different allosteric conformers of the mannose-specific bacterial adhesin FimH – the most common cell attachment protein of Escherichia coli and other enterobacterial pathogens. Included are types of antibodies that activate the FimH function via interaction with ligand-induced binding sites or by wedging between domains as well as antibodies that inhibit FimH through orthosteric, parasteric, or novel dynasteric mechanisms. Understanding the molecular mechanism of antibody action against allosteric proteins provides insights how to design antibodies with a desired functional effect, including those with neutralizing activity against bacterial and viral cell attachment proteins.
