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 switch time for High to Low performance of this part.
