MET17 selection marker

Usage

The MET17 gene, found in the Saccharomyces cerevisiae yeast, encodes a bifunctional enzyme with O-acetylserine and O-acetylhomoserine sulfhydrylase activities involved in methionine and cysteine metabolism. It catalyzes the reaction between acetylated serine or homoserine with thiol to produce the corresponding amino acid and is localized to the cytoplasm and plasma membrane[3].

MET17 gene serves as a commonly used yeast selectable marker. When MET17 gene is inserted into an integrative or replicative plasmid, MET17 allows to counter-select the cells that acquired the prototroph character for methionine. Those cells should not have the functional HIS3 gene in its genome[1].

The sequence contains MET17 specific promoter, MET17 coding sequence, and MET17 terminator.

Experiments

Team iGEM Toulouse 2020 did not have sufficient time to complete the cloning and hence, to test this part functionality.
