The LMU-Munich team is exuberantly happy about the great success at the World Championship Jamboree in Boston. Our project Beadzillus finished 4th and won the prize for the "Best Wiki" (with Slovenia) and "Best New Application Project".

Our project Beadzillus is composed of several modules. Click on the symbols to learn more about their function. The idea of Beadzillus is to enrich the [http://partsregistry.org/Main_Page partsregistry] with new BioBricks that are needed for the work with B. subtilis and show how its unique features lead to new creative ideas. We use the spores of B. subitlis to establish a platform for protein display.

-=== Clone Vectors ===
-Part of establishing ''Bacillus subtilis'' to the BioBrick mode is to modify standard vectors of ''Bacillus''. We will mutate prohibited restriction sites (EcoRI, XbaI, SpeI, PstI) and excise redundant parts of the vectors.

-=== Evaluate Promoters ===
-Another goal is to produce promoters of ''Bacillus subtilis'' in BioBrick mode and to evaluate them. We will amplify them from the ''Bacillus'' genome and clone them upstream of reporter genes (GFP, lux operon, lacZ) to measure their activity in ''Bacillus subtilis''.
-=== Fuse Spore Coat Proteins ===
+<div class="box">
+====Project Navigation====
-There are several different coat proteins in the spores of ''Bacillus subtilis.'' We chose CotZ and CgeA, which are located in the outermost layer of the spore coat. Our first step will be to  fuse GFP to these proteins to see if they appear on the spore surface and if there is any effect on spore formation. The next step will be to fuse proteins with special features to CotZ and CgeA to produce functional "SporoBeads."

-=== Stop Germination ===
+</div>
-To stop the SporoBeads from germinating, we have thought of two different manipulations. First, we will knock-out several genes which are necessary for all germination pathways, namely the cortex hydrolysis. Several gene deletion combinations will be tested for their outgrowth rates.
-As a second mechanism to prevent germination, spores which begin to germinate despite the gene deletions shall be killed by an endotoxin system. Here, we will work with a sigma-factor from a different species which works in ''Bacillus subtilis'' but does not interfere with endogenous promoters. This sigma factor is placed downstream of a promoter that is strongly activated by sigmaG, the last active sigma factor in the endospore. Therefore, the alternative sigma factor is produced right before sporulation. The bacteria also have a second construct inserted into their genome: a promoter activated by the alternative sigma factor which leads to the transcription of an endotoxin. So, if a spore starts metabolism, the toxin gene will be activated and kill the germinating spore.
