YamilCP is a CDS of blue chromoprotein in S. cerevisiae.
YamilCP is a CDS of chromoprotein which can exhibit strong blue color in S. cerevisiae. It was optimized for S. cerevisiae on the basis of amilCP(BBa_K592009) which is encouraged by Team Uppsala-Sweden 2011. It acts as a reporter in our project to determine the function of Gal1 promoter (pGAL1) and Met3 promoter (pMet3).

2019 SCU-China:
The yamilCP was improved from amilCP(Part:BBa_K592009), which is a blue chromoprotein gene from Acropora millepora submitted by Team Uppsala-Sweden 2011.
We expected amilCP to be expressed efficiently in S. cerevisiae, so we chose amilCP to be improved. We processed codon optimization on original amilCP sequence and added a consensus sequence (AAAAAA) for its usage in S. cerevisiae. And the new sequence was named yamilCP.
We respectively cloned the amilCP and yamilCP on the vector of pYES2-NTA.There are the maps of pYES2-amilCP and pYES2-yamilCP (Figure.1 and Figure.2). And we verified the construction of them by double restriction enzymes digestion and sequencing (Figure.3).
Then we transformed pYES2-amilCP and pYES2-yamilCP into S. cerevisiae respectively and successfully observed the expression of blue chromoprotein (Figure.4).
To test the expression of pYES2-amilCP and pYES2-yamilCP in S. cerevisiae, we transformed them into S. cerevisiae BY4741 and used galactose to induce blue chromoprotein expression. After 10 days, we observed blue colony on the pYES2-yamilCP plate at first and there was no blue colony on the pYES2-amilCP plate, which confirmed that yamilCP express more quickly than amilCP (Figure.5). It shows that our improvement is successful.
As the result, the improved yamilCP was successfully expressed, and the expression of yamilCP is more quickly than that of amilCP in S. cerevisiae.
