pSB1KY-TRP1

The pSB1KY-TRP1 is a shuttle plasmid backbone suitable for the iGEM RFC1000 assembly in Saccharomyces cerevisiae with TRP1 auxotrophy. It was adapted from pSB1K plasmid and optimized to be expressed in Escherichia coli cells and S. cerevisiae with trp1 mutations.

Usage and Biology

TRP1 codes for phosphoribosylanthranilate isomerase that catalyzes the third step in tryptophan biosynthesis [1]. It complements trp1 mutations allowing yeast to grow on media with no tryptophan supplements.

The pSB1KY-HIS3 was assembled similarly to pSB1KY-URA3.
