Abstract
The plasmid-mediated mcr-1 gene encodes a phosphoethanolamine transferase that confers resistance to polymyxins. The mcr-1 gene is associated with insertion sequence ISApl1 (IS30 family). In vitro mobilization assays demonstrated the functionality of the composite transposon structure ISApl1-mcr-1-ISApl1 Transposition generated a 2-bp duplication and occurred in AT-rich DNA regions. This is the first report demonstrating the mobility of the mcr-1 gene by transposition.Keywords: ISApl1; composite transposon; mcr-1; plasmid; polymyxins; transposition
