This page gives a basic overview about our cell-free Bisphenol A biosensor system and the BioBricks we have used. A more detailed description of the biosensor system can be found in our project description and in the Bisphenol A, S-layer and NAD+ detection background subsections.

How our system works
![](/wiki/images/d/d7/IGEM_Bielefeld_Project.jpg)
Figure 3: Visualization of our cell-free Bisphenol A biosensor system with all essential components. Bisphenol A (BPA) is reduced by the electrons from NADH transferred by the ferredoxin-NADP+ oxidoreductase (FNR, <partinfo>BBa_K525499</partinfo>), ferredoxin (Fd, <partinfo>BBa_K123000</partinfo>) and cytochrome P450 (CYP, <partinfo>BBa_K123001</partinfo>) which are fused to a S-Layer protein. The molecular beacon (hairpin structure) binds two short DNA oligos. The NAD+-dependent ligase (LigA), which is also fused to a S-Layer protein, ligates the two oligos so that the hairpin structure opens up and the fluorophore is able to emit light after extinction.
