Technical Abstract: Selective recognition is an important factor in the development of materials to bind and detect mycotoxins, including fumonisins. At the molecular level, selective recognition can be modeled as the interaction of the mycotoxin with the binding material. This type of molecular recognition is highly dependent on the conformation of the mycotoxin and the binding site. In addition, solvent has an effect on conformations of the interacting species and the binding interactions. In our computational studies, we identified several stable conformations for fumonisins A1, A2, B1, B2, and B3 in explicit water and in vacuo. Calculations of the preferred conformations of fumonisins interacting with potential binding sites will provide useful information for the design of fumonisin selective binding materials.
