Design Notes
This part is a self-cleaving fusion protein. It has been designed thanks to the results of the publication
Banki et al.
The phasin protein binds to the granule membrane. The second phasin makes the binding stronger and then increases the rate of purified protein during the step of granules extraction. The intein is a self-cleaving protein which breaks under pH=6 and allows the release of the protein of interest fused at the end of the sequence The prefix biobrick standard used contains a perfect RBS. This part should have been synthesized by Mr gene in once but due to technical issues we had to redesign two separated fusion biobricks and ligate them. The sequencing of this part confirmed the expected sequence.
The suffix is a silver standard fusion suffix: 5' ACTAGT A GCGGCCG CTGCAG 3'.
The phasin sequence is the same as the biobrick BBa_K208001 from the Utah 2009 team.
The intein is from the self-cleaving protein sequence delta.I-CM mini intein from mycobacterium tuberculosis described in this patent. We contacted David W. Wood to confirm the exact sequence they used.
The intergenic regions are the same as the one described in Banki et al.
