Design Notes
The gene has been assembled by using overlapping oligos and Gibson assembly. The restriction site NheI has been added to get rid of the STOP codon. It is an improvement in the biobricks system, because it can be used to reassemble the coding sequence. For example in our project, another copy of the gene can be added just after the first one, so influence of the length of the final polymer on mechanical properties can be determined.
The design and in-silico cloning has been performed on Genome Compiler
Consensus sequence:
In the literature we found out that the natural elastin has some repetitions, in particular the sequence VPGXG seems to be repeated. X is V, L, or A, and it represents 9% of the whole polypeptide. This particular sequence were translated with codon optimization for E.coli to produce a (VPGXG)x protein. Elastin properties were checked to see if they are still existing after cloning into bacteria to produce the recombinant protein named elastin like polypeptide (ELP).
