LacI-Lac repressor GB compatible with B3-B5
Coding region for the LacI protein without an RBS.
Usage and Biology
The lac inhibitor and its operator is usually use for gene regulation and together they form a genetic circuit which called : the lac operon. In bacteria ,in abundance of lactose , lactose binds to lacI and the lac operon is activated. In synthetic biology , as an inducer we use IPTG, which doesn’t degraded in the cell , instead of lactose . IPTG is a molecular mimic of a lactose metabolite, which activates transcription of the lac operon. The lacI has the ability to bind to the lac operator (BBa_R0010 and BBa_R0011 hybrid regulator) inhibiting the expression of the desirable transcription unit.
