BBa_K2282006 (AmilCP + Ds box) with BBa_K2282001 (CspA promoter + Up element)

Usage and Biology

This sequence is used to evaluate our cold shock response. The UP element is believed to stimulate the transcription of the CspA gene at a cold temperature, although some reports conclude the opposite (Phadtare et al., 2005). This promoter plays a role in transcription, though does not relate to the translation regulation (DSBox, 5’UTR). The CspA promoter is considered a strong promoter (Mitta et al., 1997). The DSBox is a cis-acting mRNA element enabling assembly of the translation pre-initiation complex, likely through interaction with ribosomal protein S1. (Studer et al 2006, Duval et al, 2013, Qu et al 2012)

Refer to the part BBa_K2282005. Only the addition of the DSBox in the AmilCP coding sequence makes the difference between this part and BBa_K2282005. Sequences of the DSBox and other cold-induced elements are very close to the parts of the iGEM10_Mexico-UNAM-CINVESTAV that can be found here : http://partsregistry.org/Part:BBa_K328003


Design consideration

The same difficulties as BBa_K2282005
