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.

  Project Specific Constructs

 Additional Bacterial Parts  Novel Zero Leak Inverter (K122007 and K122006)



 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.



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).
