Fig. 3.

Major structural proteins of the toga. (A) Ompα1–3 and β-barrel proteins detected in the toga with their predicted tertiary structures. (B) Mass spectrometry-based proteomics reveal Ompα1–3 and β-barrel proteins are enriched in the toga. Ompα, orange dots; β-barrel proteins, purple dots. The significance cut off at P > 0.05 is indicated with a horizontal dashed line at 1.25 −log10 P-value. The zero-fold change is indicated with a vertical dashed line. (C) Homology conservation of toga-associated proteins across the Thermotogae phylum. PSI-BLAST hits are shaded by % amino acid similarity to T. maritima proteins. Species (Top) and family (f__) names (Bottom) are shown.
