Analysis of IsItABarrelDB by phylum. (A) The distribution of the eleven protein types and unclassified IsItABarrelDB TMBB sequences among 38 phyla. A red to blue scale indicates greater to fewer numbers of that protein type or no proteins of that type (white). Phyla are organized by Terrabacteria and Gracilicutes (gray and black dots, lowest row), and colored dots that show clades within those categories (middle row), clades are as previously described (48, 49) FCB–Fibrobacteres/Chlorobi/Bacteroidetes, PANNAM–Proteobacteria/Acidobacteria/Nitrospinae/Nitrospirae/Aminicenantes/Methylomirabilis, PVC–Planctomycetes/Verrucomicrobia/Chlamydiae, DST–Deinococcus-Thermus/Synergistetes/Thermotogae, CCD–CPR/Chloroflexi/Dormibacteraeota, CMS–Cyanobacteria/Melainabacteria/Margulisbacteria-Saganbacteria. Dots are also used to indicate the presence of a classic β-signal (top row, red, and green). The Unclassified type across all phyla includes 274,245 sequences. (B) Sequence logos of the prototypical β-signal of each phyla that has a clear traditional β-signal. Logos as described in Fig. 2D. No logo plot was created for Atribacterota because it only contained two proteins.
