Figure 1

Phylogenetic placement of NAG1. In all the phylogenies, NAG1 and its sister clade are shown in bold font. Taxa not part of the TACK superphylum are shown in grey. Major taxa have been collapsed to improve readability. Numbers on branches represent bootstrap support (a–e) or posterior probability (f). Support for the branch linking NAG1 and its sister clade is shown in bold. Scale (number of substitutions per site) is shown next to each tree. Full trees showing all included organisms are displayed in Supplementary Figure S3. (a) ML phylogeny inferred from 33 universal r-proteins. Numbers in italics next to taxa names show the mean genomic GC content in the taxa and, whenever applicable, the range (between parentheses). (b, c) ML phylogeny inferred from the same proteins, keeping only the most and the least compositionally biased half of the sites, respectively. (d) ML phylogeny from a set of 25 conserved non-r-proteins, filtered for horizontal gene transfers. (e) ML phylogeny of the concatenation of 32 of the 33 r-proteins from panel (a) and the 25 non-r-proteins from panel (d). (f) Bayesian phylogeny inferred from the concatenated alignments of the sequences of the 16S and 23S rRNA sequences.

Overview of non-universal r-protein occurrence in different archaeal lineages. The figure is in part based on a study by Yutin et al. (2012) but has been updated to include novel members of the archaea, including NAG1. Black diamonds denote the presence of respective r-proteins.
