Part:BBa_K1045011

Designed by: iGEM Team Göttingen 2013   Group: iGEM13_Goettingen   (2013-09-20)

Promoter reverse
BBa_K1045011 encodes for a weak promoter based on BBa_J23117 promoter from the well characterized Anderson promoter collection. Yet, the promoter in BBa_K1045011 is inverted. We improved the inverted promoter BBa_J23117 by adding additional base pairs upstream of the inverted promoter region. These additional base pairs will allow cloning of this promoter directly in front of another promoter oriented in the opposite direction. This way, a vector with two different expression units oriented in diverging directions can be created. The extra bases might prevent that the binding of the RNA polymerase to the usual promoter influences the binding of the RNA polymerase to the inverse promoter in BBa_K1045011 (for an example see BBa_K1045017, a detection system for c-di-AMP).

Why this part is improved:

1. BBa_J23117 was inverted (pre- and suffix switched).

2. BBa_K1045011 has additional bases in front of its promoter region. These bases allow to clone this promoter in front of a promoter oriented in the other direction.

3. Since the sequence is just inverted between the pre- and suffix, this promoter can be used with other inverted biobricks (for example: BBa_K1045001).
