Gibson Assembly facilitates bacterial allelic exchange mutagenesis.

Abstract excerpt

Allelic exchange mutagenesis that relies on RecA-mediated homologous recombination up- and downstream from the targeted gene is a generalizable method of site-specific bacterial gene knock-out and knock-in. However, generation of a mutagenic DNA construct (alternative allele flanked by regions surrounding the gene target) and subsequent mutant selection are laborious procedures. Here we demonstrate allelic...
