Design and Properties

We use ADH1 promoter to promote the expression of FucT2.

We tested the ADH1 promoter: we transform the gene "ADH1 promoter and FucT2 (https://parts.igem.org/Part:BBa_K4081998#BBa_K4081998])" into Saccharomyces cerevisiae BY4741 by lithium acetate conversion method to integrate the genes into the genome of BY4741 for expression.The result of SDS-PAGE showed that we successfully expressed FucT2 by ADH1 promoter(figure1).

Experimental approach

1.Construct recombinant plasmids. Get GAP promoter from vector PML104. Get TEF1 promoter from the genome of Saccharomyces cerevisiae BY4741. Get ADH1 promoter from vector pAUR123. Company synthetic genes of FKP, LAC12 and FucT2. Use vector pAUR123 to construct our plasimd “pAUR123-pGAP-FKP-pADH1-FucT2-pTEF1-LAC12”.

2.Transform the product (2.5μL) into DH5α competent cells (50μL), grow cells on agar plates (containing Ampicillin). Incubate plates at 37°C overnight. Colonies were screened by colony PCR and then grown at 37℃, 200rpm. Plasmids were extracted and sent for sequencing.

3.PCR the genes “pGAP-FKP-pADH1-FucT2-pTEF1-LAC12” and the resistance gene AurR from the plasmid with homology arms of BY4741. Transform it into BY4741 by lithium acetate conversion method to integrate genes into the genome of BY4741 for expression. Screen for transformants by AbA-YPD selection medium.

4.Extract yeast total protein. Use SDS-PAGE to test whether the three proteins(FKP, LAC12, FucT2) are successfully expressed.
