Our project was in a sense, a continuation of Uppsala 2013 and Slovenia 2010 team's legacy. We have worked with the Slovenia 2010 strain, and integrated the genes into the chromosome to stabilize production. We improved the crocin biosynthetic pathway that Uppsala 2013 had problems with by identifying and working with the correct genes in the pathway i.e CaCCD2 and CsADH2946. We have done codon optimization of all the enzyme sequences and created new biobricks with them. Another improvement we made was to add different promoters to the biobrick. In all of our enzymes, we have worked with both constitutive and inducible promoters. Since our enzymes were poorly characterized , we added a his-tag to them to make the purification more achievable. The addition of his-tag was done after consulting the structural models of the enzymes. For example, BBa_K2423008 is an improved version of BBa_K1033112 and a slightly modified version of BBa_K2423002 (different promoter and RBS).

-       <div class="textbox">Our project was in a sense continuation of Uppsala 2013 and Slovenia 2010 legacy. We have worked with the Slovenia 2010 strain and transported it to the chromosome to stabilize production. We have also worked with the three enzymatic steps that Uppsala 2013 had problems with. We have done codon optimization of the enzymes and created new biobricks with improved sequence. Another improvement we made was to add different promotors to the biobrick. In all of our enzymes we have worked with both constitutive and inducible promotors. Since our enzymes were poorly described and previously problematic to purify we added a his-tag to them to make the purification more achievable. The addition of his-tag was done after consulting the structural models of the biobricks.  For example, <a href="http://parts.igem.org/Part:BBa_K2423008">BBa_K2423008</a> is an improved version of <a href="http://parts.igem.org/Part:BBa_K1033112">BBa_K1033112</a> and a slightly modified version of <a href="http://parts.igem.org/Part:BBa_K2423002">BBa_K2423002</a> (different promoter and RBS).
