     <p>S. cerevisiae is an incredible eukaryotic model organism, but its potential for synthetic biology is hidden by the lack of modular biobrick parts for this system. In addition to introducing novel genes into the registry, this year we added  new yeast promoters, yeast terminators, a Histidine tag and 2 micron ORI, two new selectible markers, and a yeast integration plasmid suitable for future yeast work. For additional foundational tools, we have added an amber suppressor biobrick with a wide range of functionality and selectible by the amber suppressed RFP.<br />

OUR TEAM:::SUMMARY ::: BACKGROUND ::: STRATEGY ::: CONSTRUCTS ::: RESULTS ::: ONGOING WORK

Constructs

Saccharomyces cerevisiae is widely used for baking and brewing, a versatile eukaryotic model system, and particularly useful for synthesizing metabolites under fermentation conditions. The microaerobic conditions of fermentation impede the oxidation of sensitive bioreactive compounds and are optimal for the de novo synthesis of resveratrol. To achieve our project goals and expand the yeast synthetic biology toolbox, we have constructed BioBricks encoding 3 yeast promoters, 3 yeast terminators, a 2-micron origin of replication, 2 selectable markers, 2 metabolic enzymes, and a yeast integration plasmid. We have also submitted two additional parts representing foundational tools, including a gene encoding an amber suppressed RFP biobrick for screening of SupF+ (Amber suppressor) genotype and an amber suppressor tRNA biobrick.


Yeast Promoters

[http://partsregistry.org/wiki/index.php?title=Part:BBa_K122000 BBa_K122000] pPGK1 ~1500 bp upstream of the PGK1 coding region. Strongly induced during fermentation. 1497bp

[http://partsregistry.org/wiki/index.php?title=Part:BBa_K122001 BBa_K122017] pGAL1 + tetO Glucose repressible / galactose inducible GAL1 promoter. An additional TetR operator site was included to allow repression by TetR. 484bp


Yeast Terminators

Amber Suppressor tRNA
[http://partsregistry.org/wiki/index.php?title=Part:BBa_K122007 K122007] The supF construct, an amber suppressor tRNA, allows for read-through at native amber (TAG) stop codons. Charges with tyrosine. 211bp
[http://partsregistry.org/wiki/index.php?title=Part:BBa_K122006 K122006] Point Mutation of RFP(13521) with incorporation of an amber stop codon at the native tyrosine required for fluorophore maturation. 923bp



Through incorporation of amber stop codons or point mutations of tyrosine codons (TAC) to TAG within the coding region, a genetic circuit can be used to add an additional level of regulation and determine whether a full protein or partial peptide with be synthesized. This design has high signal-to-noise ratio, with virtually no leaky expression.




Arfp.jpg

The Amber suppressed Red Florescent Protein (ARFP) has no virtually expression in SupF- (2) cells while visually apparent levels of red pigment is present in SupF+ cells (4). ARFP expression was compared against wtRFP expression in both cell types (1 and 3).
