Description
This device allows recombination at the inverted repeats of the dif-site so that the flanked sequence between (the lac promoter) is inverted and can activate the downstream reporter gene (YFP). It was planned as the proof-of-concept for Edinburgh 2007 project.
Notes
Rumour (unpublished data) has it that the flanked DNA needs be of certain lenght to allow it to form a loop and subsequently invert. 200bp is minimal so the Plac was extended to include nonfunctional LacZ C-terminus.
Source
Dif-sites and the Plac are innate E. coli K12 loci. See BBa_E0430 for details about YFP.
