HIS3 selection marker

Usage

HIS3 gene, found in the Saccharomyces cerevisiae yeast, encodes a protein called Imidazoleglycerol-phosphate dehydratase which catalyzes the sixth step in histidine biosynthesis(1). It is analogous to hisB in Escherichia coli.

HIS3 gene serves as a commonly used yeast selectable marker. When HIS3 gene is inserted into an integrative or replicative plasmid, HIS3 allows to counter-select the cells that acquired the prototroph character for histidine so that they can grow without histidine addition in the medium. Those cells should not have the functional HIS3 gene in its genome[1].

The sequence contains HIS3 specific promoter, HIS3 coding sequence, and HIS3 terminator.

Experiments

We used the HIS3 selectable marker for the integration of the part [parts.igem.org/Part:BBa_K3570000 BBa_K3570000] to improve the mevalonate pathway. The integration was a success.The transformed yeast can grow on a minimal medium without histidine.
