Endow the E.coli engineered strain(CL-1) the ability of chemotaxis


What it is

Composite part enables the chemotaxis of our engineering bacteria could be regulated by IPTG and L-Arabinose; pBAD and pLac promoters control the expression of Lac I and CheZ.


What it does

when L-Arabinose is added, pBAD promoter is activated, expressing Lac I, inhibiting the expression of CheZ. When IPTG is added, IPTG combines with Lac I, forming a complex, thus relief the inhibition and the CheZ express, make the ability of chemotaxis recover.


How to use it in their project

Use IPTG as an inducer and L-Arabinose as an inhibitor to take control of the chemotaxis of the engineering bacteria.
