Figure 1 (a) Genetic backbone of pECPB39 (MG886287) and pKP13a (CP003996) plasmids. In pECPB39, the ΔproP-mcr-5.3-chrB array has been incorporated into the pKP13a backbone. In fact, the mcr-5.3 gene is embedded within a Tn3-family transposon with a 38 bp IRL, as previously reported.<sup>3</sup> DUF, domain of unknown function proteins. (b) Comparison of MCR-5-type phosphoethanolamine transferase proteins of S. enterica subsp. enterica serovar Paratyphi B and E. coli strains identified in Germany<sup>3</sup><sup>,</sup><sup>4</sup> and Brazil (this study). The position of the amino acid deletion in MCR-5.2 (Glu233) is indicated by a dash (highlighted in grey), whereas the amino acid substitution in MCR-5.3 (Ala414Ser) is indicated in bold (highlighted in grey).
