Diversity of Sal-type proteins. An unrooted, maximum likelihood phylogeny of novel and variant Sal-type proteins and other selected ABC-F proteins involved in antibiotic resistance shows a bipartite structure of the Sal-type (ARE6) subfamily, with Sal(A)–(C) and Sal(D)–(E) falling within two respective, fully-supported clades. Branch lengths are proportional to the number of amino acid substitutions as per the lower left scale bar. Numbers on branches indicate percentage bootstrap support values.
