LacIM1 shows weaker repression than LacIWT because it has a lower affinity to lac promoter [1].  Though this part was registered by USTC(2008), it was not well characterized in their wiki.  Therefore, we characterized this part.

Characterization of BBa_K395400

Tokyo Tech iGEM2010

In order to characterize K395400, LacI Mutant, we constructed BBa_K395401 combining I0500 and K082026(K395400) on pSB1A3 and used BBa_I20260 as a positive control and used promoterless gfp on pSB3K3 as a negative control. Furthermore, we constructed BBa_K395402 combining I0500 and BBa_I732820(LacIWT) on pSB1A3 as a control experiment. As a GFP reporter, we used BBa_I7106 on pSB3K3. In order to measure the function of K395400), we introduced BBa_I7106 (lacI+pL-rbs-GFP-ter) on pSB3K3 and BBa_K395401/BBa_K395402 into DH5α.

We confirmed that product of lacIM1 shows weaker repression to lac promoter than its wild type.
