YaxAB Pore (image) Technical University of Munich (TUM) Share Print E-Mail Caption Pore-forming toxins are common bacterial poisons. They attack organisms by introducing holes in cell membranes. A team of scientists at the Technical University of Munich (TUM) has now unraveled the mechanism of action for one of these toxins. The picture shows the two components YaxA (blue) and YaxB (purple) and a pore built up from these subunits.
