Design Notes

We noticed that, when cloning the DarR operator via hybridization oligos, it was difficult to obtain transformants. The DarR operator harbors a palindromic sequence. Hence, the inefficient transformations could indicate that secondary structures which might be formed by the palindromic sequences of these hybridization oligos interfere with the transformation.

The sequence of this part corresponds to the sequence of the DarR operator upstream of darR, which was published by Zhang et al. in 2013. The part was generated using hybridization oligos purchased from Sigma-Aldrich.
