Dimerization of the copper metallothionein 1 : CUP1-(AP)7-CUP1

Copper metallotionein 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) in order to be displayed on the outter yeast cell surface. In order to improve the copper fixation efficiency in yeast, CUP1 was linked to a second sequence of the same protein. The linker is a rigid linker and is made of seven successive AP amino acid sequences. 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.
