Arabinose inducible Reflectin A2 generator

Produces Reflectin A2 protein on addition of arabinose.

The reflectin gene is under the control of the pBAD promoter BBa_I0500, which is tightly controlled by two factors:

  • L-arabinose monosaccharide taken up by the cell from the medium, which acts as an inducer.
  • AraC protein included in the I0500 biobrick, which acts an a repressor.

Therefore, the araC-pBAD system offers regulatable control of gene expression in the presence of the inducer and highly repressed in the absence of the inducer. Read more about [http://2011.igem.org/Team:Cambridge/Experiments/Low_Level_Expression the pBAD and arabinose system in E.coli].

Usage and Biology

Best used in an E. coli chassis such as strain [[http://cgsc.biology.yale.edu/Strain.php?ID=111773 BW27783], with constitutive expression of an Arabinose transporter. See our experience of pBAD for some issues with tuning expression levels.
