Figure 3. Conserved genomic locus for cell envelope components.
Co-localization of the genes coding for LPS synthesis and transport, OMP assembly and structural OMPs in the Negativicutes and the Halanaerobiales. Representatives of the 2 families of Negativicutes and the 2 families of Halanaerobiales are shown (for full distribution and accession numbers see Supplementary file 1). Genes are colored according to their functional class: LPS synthesis and transport (green), OMP assembly (blue), flagellum (light pink), OM-PG attachment (red), hypothetical (brown), efflux (purple) (see text for discussion). White boxes indicate proteins not known to being related to the OM or non-conserved proteins whose connection with the OM is unclear. The figure was obtained by EasyFig (Sullivan et al., 2011), where vertical lines represent BLAST hits with a cutoff of 0.0001.
