PlacIq-LacI-Plac-cI-λPR dual inverter
The dual inverter system consists of PlacIq-LacI-Plac-cI-λPR.
The lacI gene is expressed from an unregulated promoter Placlq, and its product LacI represses the Plac promoter. Likewise, the Plac promoter controls the expression of the cI gene, and its product CI represses the PR promoter. The PR promoter controls the production of the red fluorescent protein (mRFP1), which represents the‘output’for the circuit, whereas the chemical inducer isopropyl β-D-thiogalactopyranoside (IPTG), which binds to LacI tetramers and renders them unable to repress Plac, provides an external control over the network and thus represents the‘input.’
