Part:BBa_K395401

pBad/araC-lacIM1

In order to measure LacIM1(BBa_K395400), we designed this part.

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_I 732820 on pSB1A3 as a control experiment. As a GFP reporter, we used BBa_I7106 on pSB3K3. In order to measure the function of lacI proteins, 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.
