Expression of CUP1 on the extracellular membrane of S. cerevisiae

This part is made of the Gal1 promoter (BBa_J63006), the A-agglutinin-binding subunit Aga2 (BBa_K416000) linked to the CUP1 copper metallotionein protein 1 (BBa_M45090) and the V5 tag (BBa_T2020).

Usage and Biology

Copper metallothionein CUP1 (BBa_M45090) is a protein responsible for copper binding protein in the yeast Saccharomyces cerevisiae. Normally expressed intracellularly, CUP1 was fused to the A-agglutinin-binding subunit Aga2 (BBa_K416000) that attaches to the yeast cell wall through disulfide bonds to Aga1p. This leads to the presence of CUP1 on the outer membrane of the cell. The goal behind it was to improve the endogenous bio-accumulation property of wild type yeast by allowing it to bind more copper ions on its external surface.

This fusion protein also contains a V5 tag (BBa_T2020) in order to check its expression by Western Blot and Immunocytochemistry. The expression is under the control of the Gal1 promoter (BBa_J63006), so that the protein is expressed only in the presence of galactose.
