Figure 3 From: Exopolysaccharide-associated protein sorting in environmental organisms: the PEP-CTERM/EpsH system. Application of a novel phylogenetic profiling heuristic A phylogenetic tree based on 16S RNA of PEP-CTERM-containing and related organisms. Species with PEP-CTERM and an EpsH homolog are labeled in green. Chlorobium tepidum, which has only the PEP-CTERM domain, is shown in blue.Back to article page
