Synthesis of the gene coding for the SLPs(BBa_K1317002)

Part:BBa_K1317001 : CDS for resilin-like polypeptide (RLP)

This part is the coding sequence for the resilin like polypeptide. This sequence was assembled from a consensus of the proresilin exon 1 from Drosophila melanogaster. This protein, in insects, allows resistance and elasticity used for jumping, flapping... The synthetic gene encodes a synthetic protein "resilin-like". The repeated aminoacids allow to retrieve these properties of resistance, resilience and elasticity, but with a minimal pattern of the original protein, which is more suited for downstream applications. It can be used to produce wire presenting these properties after wet-spinning.

Design Notes

The gene used to assemble the biobrick has been provided by GenScript even if the assembling strategy succeeded It allows us to have the proper sequence without mutation and with sequencing results.
The strategy of our assembly is described below anyway. The gene was synthesized by ordering specific oligo with overlapping regions, and by adding a NheI site for further fusing proteins.
We used the pro-resilin exon 1 from Drosophila melanogaster. We identified a repetitive pattern, PSXXYGAP. So we blast it against the protein database of pro-resilin to check if the pattern was conserved within different species or specific to Drosophila.

We have taken XX randomly and we brought out conserved pattern so we used it to do our resilin like polypeptide with the following pattern: (RLP) MW-[(PSSSYGAP)(PSNSYGAP)(PSTSYGAP)(PVAYGAP)]3

The literature delivers some mechanical properties concerning native resilin as high resilience (<90%) that allows the protein to recover its initial folding after a high tensile stress. Thus it can be an interesting characteristic to show and use, so we wanted to test it on our RLP.
