<p align="justify">Therefore we first fused ''cotZ'' to its two native promoters, P<sub>''cotV''</sub> and P<sub>''cotYZ''</sub>, and to P<sub>''cgeA''</sub>, which regulates the transcription of ''cgeA''. For cgeA we only used its native promoter P<sub>''cgeA''</sub> and the stonger one of the two promoters of the ''cotVWXYZ'' cluster, P<sub>''cotYZ''</sub> (for more details see [https://2012.igem.org/Team:LMU-Munich/Data/crustpromoters crust promotor evaluation]. While [http://partsregistry.org/Part:BBa_K823039 ''gfp''] was ligated to the terminator B0014 (see [http://partsregistry.org/wiki/index.php?title=Part:BBa_B0014 Registry]). When these constructs were finished and confirmed by sequencing, we fused them together applying the Freiburg standard to create in frame fusion proteins, flanked by one of the three promoters and the terminator.This way we created C-terminal fusion proteins.

<br>But as we did not know if C- or N-terminal fusion would influence the fusion protein expression, our second aim was to construct N-terminal fusion proteins as well. For this purpose we wanted to fuse the genes for the crust proteins ''cotZ'' and ''cgeA'' to the terminator and ''gfp'' to the three chosen promoters. Unsuccessfully, there occured a mutation in the XbaI site during construction of ''gfp'' in Freiburg Standard which is why we were not able to finish these constructs.

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".
