Use of bacteriophage lambda recombination functions to promote gene replacement in Escherichia coli

J Bacteriol. 1998 Apr;180(8):2063-71. doi: 10.1128/JB.180.8.2063-2071.1998.


Replacement of Escherichia coli's RecBCD function with phage lambda's Red function generates a strain whose chromosome recombines with short linear DNA fragments at a greatly elevated rate. The rate is at least 70-fold higher than that exhibited by a recBC sbcBC or recD strain. The value of the system is highlighted by gene replacement with a PCR-generated DNA fragment. The deltarecBCD::Plac-red kan replacement allele can be P1 transduced to other E. coli strains, making the hyper-Rec phenotype easily transferable.
