Dissemination and Mechanism for the MCR-1 Colistin Resistance
Fig 5
The method of maximum likelihood tree is applied here. The scale bar corresponds to a 100% difference in compared residues, on average, per branch length. The members in this phylogenetic tree can be grouped into two clades (one is annotated as Phosphoethanolamine transferases [PEA transferase], and the other denotes Sulfatases [marked in pink]. Of note, the group of PEA transferase can be divided into two sub-clades: Sub-clade I (marked in blue) with MCR-1 and Sub-clade II (highlighted in green) with Neisseria gonorrhoeae LptA.
