Lux pL controlled luxR with lux pR controlled AHL degrading enzyme AiiA(lva tag).

The F2621 BioBrick device contains a lux pL regulated luxR repressor/activator and a lux pR promoter that is linked to an 3OC6HSL, an AHL autoinducer molecule, synthetase. The lux pL promoter yields a weak constitutive downstream expression. When LuxR and 3OC6HSL are produced, the lux pL promoter, however, will be repressed by a complex of the two. If 3OC6HSL is present in the cell, the autoinducer inactivation enzyme A (aiiA), with an LVA Tag, will inactivate the 3OC6HSL autoinducer molecules.
