3' Integration Sequence for the amyE Locus of B. subtilis
Integration sequences allow DNA to be incorporated into the chromosome of a host cell at a specific locus using leading (5') and trailing (3') DNA sequences that are the same as those at a specific locus of the chromosome. The 5' integration sequence can be added to the front of a BioBrick construct and the 3' integration sequence specific for this locus (BBa_K143001) to the rear of the BioBrick construct to allow integration of the BioBrick constructs into the chromosome of the Gram-positive bacterium B. subtilis at the amyE locus.
The amyE locus was the first locus used for integration into B. subtilis by Shimotsu and Henner and is still commonly used in vectors such as pDR111, pDL and their derivatives. Integration at the amyE locus removes the ability of B. subtilis to break down starch, which can be assayed with iodine as described by Cutting and Vander-horn. For the iGEM 2008 competition, the Imperial Team used the 5' and 3' integration sequences for the amyE locus to integrate genetic construct into the B. subtilis chromosome.
