Tight pBAD with araC

Non leaky pBAD promoter with araC constitutively expressed. This biobrick is the same as part:BBa_K808000 but with a change in pBAD promoter and another sequence annotation. The promoter is taken from the pBAD SPL col. 10 from [http://2013.igem.org/Team:DTU-Denmark 2013 DTU iGEM team].

Characterization

Non-induced activity vs inducted activity for a variety of promoters built from the pBAD_SPL. This biobrick (BBa_K1067007) is built with colony 10. The diagonal line represents 1:1, on which the constitutive reference promoter sits. The horizontal blue line represents the induced activity of BBa_K808000.

The promoter for this biobrick was taken from a synthetic promoter library built to vary the expression and leakiness of Part:BBa_K808000. The colonies that we selected all show less activity than the the constitutive promoter, and when induced, show higher activity than the constitutive promoter. The promoter taken for this part shows high induced activity and low basal (non-induced) activity. For detail see the graph above. This makes it ideal for expression of lethal proteins and to tightly control expression.

For further characterization and information see the pBAD SPL page or go to the 2013 DTU [http://2013.igem.org/Team:DTU-Denmark/pBAD_SPL wiki].
