Xylose Inducible Promoter for Staphylococcus aureus
This sequence contains the T5X xylose inducible promoter and the xylose promoter repressor, XylR, for Staphylococcus. It has been shown by Forsyth et al. (2002) that 2% xylose in LB is sufficient to generate significant expression downstream of this promoter (Forsyth et al, 2002). In the absence of xylose, XylR represses activity by binding to the promoter region. Furthermore, glucose was shown to repress the activity of this promoter (Wieland et al., 1995).
Our team obtained the sequence for this part from Dr. Donegan from the Ambrose Lab at The Geisel School of Medicine, Dartmouth. This part was synthesized by Bio Basic. By doing so, we were able to remove 3 illegal sites.
