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 Bw27783, with constitutive expression of an Arabinose transporter. See our experience of pBAD for some issues with tuning expression levels.
