Part:BBa_C0012

lacI repressor from E. coli (+LVA)

Coding region for the LacI protein with an LVA degradation tail and without an RBS. LacI binds to the pLac regulator BBa_R0010 and PLlac01 hybrid regulator BBa_R0011 and inhibits transcription. [http://openwetware.org/wiki/IPTG IPTG (Isopropylthiogalactoside)] binds to LacI and inhibits its operation, therefore promoting transcription.

A rapid degradation tail (LVA) has been added to improve the High to Low performance of this part.

Usage and Biology

This particular LacI protein is derived from e.coli and contributed by Michael Elowitz (see Part Design for more information)
