Fig. 4

A Peptide correlation map colored by family-level taxonomic annotations, showing that the map broadly corresponds to taxa sources of peptides. The areas highlighted in panels (B–E) are boxed with dashed lines. B–E Zoomed-in sections of the peptide correlation map for peptides from the different families: B Burkholderiaceae, C Eggerthellaceae, D Bacteroidaceae, and E Lachnospiraceae. Peptides are colored by genome-level taxonomic annotations. F Peptide correlation map colored by functional annotations (COG categories), showing no overall clustering based on functional associations.
