Regulatory

Part:BBa_K772104

Designed by: Mustafa Elitok   Group: iGEM12_Fatih-Medical   (2012-10-05)

pLac IPTG inducible generator

This part is an inverting regulator sensitive to LacI and CAP. It contains two protein binding sites. The first binds the CAP protein, which is generally present in E.coli and is asocciated with cell health and availability of glucose. The second binds LacI protein. This part also produces LacI protein as an oscillator which results that as LacI protein is synthesized, the promoter wil be inhibited until the presence of IPTG. The inhibition will decrease the production of LacI which leads to the synthesis of this inhibitor.

>In the absence of LacI protein and CAP protein, this part promotes transcription.

>In the presence of LacI protein and CAP protein, this part inhibits transcription.

>LacI can be inhibited by IPTG.

>LacI is coded by BBa_C0012
