Part:BBa_K4035013

Expression of the CUP1-(EAAAK)4-CUP1 dimer 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 dimer protein CUP1-(EAAAK)4-CUP1 (BBa_K4035006) and the V5 tag (BBa_T2020).

Usage and Biology

Copper metallotionein CUP1 (BBa_M45090) is a protein responsible for copper binding protein in the yeast Saccharomyces cerevisiae. In order to increase the copper retrieval efficiency, two copies of CUP1 were linked together and expressed at the outter surface of S. cerevisiae. Aga2 attaches to the yeast cell wall through disulfide bonds to Aga1p. The fusion of the dimer and Aga2 then leads to the presence of the CUP1 dimer on the outter membrane of the cell. This fusion protein also contained a V5 tag in order to check its expression by Western Blot and Immunostaining. The expression was under the control of the Gal1 promoter, so that the protein was expressed only in the presence of galactose.
