<p align="justify">The aim of this project part is to create spores that display fusion proteins on their crust. There are several different proteins forming the spore coat layers of ''Bacillus subtilis'' spores. On the outermost layer, the so called spore crust, the CotZ and CgeA proteins are located ([http://www.ncbi.nlm.nih.gov/pubmed?term=imamura%20et%20al.%202011%20spore%20crust Imamura et al., 2011]).This is why we used them to create functional fusion proteins to be expressed on our '''Sporo'''beads.

The gene ''cgeA'' is located in the ''cgeABCDE''cluster and is regulated by its own promoter P<sub>''cgeA''</sub>. The cluster ''cotVWXYZ'' contains the gene ''cotZ'' which is cotranscribed with ''cotY'' regulated by the promoter P<sub>''cotYZ''</sub>. Another promoter of this cluster P<sub>''cotV''</sub> is responsible for the transcription of the other three genes. Those three promoters were evaluated with ''lux'' reporter genes to get an impression of their time of activation and their strength (see for more details [[Bacillus BioBricks]]) so they could be used for expression of spore crust fusion proteins.

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."
