6The team
In 2011 a student command unit locked themselves in the Bielefeld University for the construction of cell-free biosensors. They promptly identified S-layer proteins as nanobiotechnological building blocks. Today still characterizing their Bisphenol A Biosensor they are the iGEM team Bielefeld. If your cells are a problem, if no one else can help and if you can find them, maybe you can hire the Bisphenol A-Team.
The project
The development of sensitive and selective biosensors is an important topic in synthetic biology. Biosensors can be applied in a wide range - from the detection of environmental toxics up to clinical diagnostics. Because cells have to sense their surroundings, there are a lot of natural systems that are similar to a biosensor. Prejudicial cellular biosensors often show negative side effects that complicate any practical application. Common problems are the limited use outside a gene laboratory due to the use of genetically engineered cells, the low durability because of the usage of living cells and the appearance of undesired signals induced by endogenous metabolic pathways.
To solve these problems, the iGEM-Team Bielefeld 2011 aims at developing a cell-free bisphenol A (BPA) biosensor based on a coupled enzyme reaction fused to S-layer proteins for everyday use. Bisphenol A is a supposedly harmful substance which is used in the production of polycarbonate. To detect BPA it is degraded by a fusion protein under formation of NAD+ which is detected by an NAD+-dependent enzymatic reaction with a molecular beacon. Both enzymes are fused to S-layer proteins which build up well-defined nanosurfaces and are attached to the surface of beads. By providing these nanobiotechnological building blocks the system is expandable to other applications.
