Arabinose inducible Reflectin A1 generator

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].
