(A) A summary diagram showing the five main clades within the family Mycobacteriaceae, now recognized as distinct genera, seen in different phylogenetic trees. The molecular synapomorphies consisting of conserved signature indels (CSIs) and conserved signature proteins (CSPs), which distinguish different clades are marked on the nodes. The members of these clades/genera also differ in their growth rates. (B) Partial sequence alignment of the ABC-F family ATP-binding cassette domain-containing protein showing a 2 aa insert in a conserved region that is commonly and uniquely present in different members of the order Mycobacteriales. The dashes (–) in the alignment show identity with the amino acids shown on the top line. The numbers with the genus name refer to different unique strains for which sequences were examined. The sequence information is shown for only 1–2 representative species from different genera that are part of this order and very few outgroup species. However, this CSI is not found in other Actinobacteria or other examined bacteria (see Figure S1) with the possible exception of Kroppenstedtia sanguinis (a Firmicute). This CSI as well as a number of other CSIs and CSPs for this order were described in our earlier work (Gao and Gupta, 2012) based on limited sequence information and most of them are still distinctive characteristics of this order.
