pGAL1 + Untagged LexA activator on pRS305

This is the LexA untagged activator driven by pGAL1. It is used as the A element in a limiter construct, modeling an endogenous transcriptional activator for our proof-of-concept.

Usage and Biology

To build a (heretofore untested) limiter, this part should be in a yeast strain with the following constructs:

A) Part:BBa_K165080 pGAL1 + Untagged LexA activator on pRS305
G) Part:BBa_K165078 LexA activable reporter on pRS306

  Into mating type a.  Knock out the Gal2 gene for a tunable level of induction.

R) Part:BBa_K165090 Gli1 bs + LexA bs + mCYC + LexA repressor (mCherryx2 tagged) on pRS306
Alpha) Part:BBa_K165095 Gli1 bs + LexA bs + mCYC + Zif268-HIV repressor (mCherryx2 tagged) on pRS303
Tau) Part:BBa_K165096 Zif268-HIV bs + MET25+ Gli1 repressor (CFPx2 tagged) on pRS304* 

  Into mating type alpha. Knock out the Gal2 gene for a tunable level of induction.

Mate the two types, select on SD-His-Trp-Leu-Ura

Inputs: Set the threshold by tuning [Met] between 0 and 500 uM Set the level of induction (A) with Galactose between 0-3%

Outputs expected:
Subthreshold [A]: CFP in the nucleus from Tau, YFP in the cytosol proportionate to subthreshold induction from G being activated by A and not repressed by R.
Superthreshold [A]: mCherry in the nucleus from Alpha and R induction. YFP in cytosol levels out at threshold limit despite rising induction.
