Introduction
CsgA is one of the several major components of E.coli biofilm. When it is co-expressed with the gene, it could bring the protein that the gene encodes to the cell surface. Mfp5 is found in mussel foot. It could induce the precipitation in vitro in the 1.5×SBF solution. According to previous experiments, the expression level of one Mfp5 gene may be insufficient to induce notable precipitation, two Mfp5 genes are incorporated in this part. This biobrick could induce the precipitation of hydroxyapatite. Sequence and Features

Usage and Viability
We designed the part as below.
After constructing the plasmids by Gibson Assembly, our team used PCR to test whether the plamids were successfully constructed. Since we omitted a part of the sequence of CsgA at first, we inserted this part of gene later and used the gel electrophoresis to detect this part. The number of bp was exactly the number we expected, proving that the construction was successful.
Since the lack of the time, we failed to carried out the experimnets to prove the function of this composite part.
