Figure 2

Compounds are grouped by known biological role including iron acquisition, host-microbe metabolic exchange, intermicrobial metabolic exchange, and intramicrobial metabolic exchange. Compound name, producing bacteria, bacterial group, and biosynthetic origin are noted. -S- is a thioether linkage. Abu, Dha, and Dhb are the non-canonical amino acids aminobutyric acid, dehydroalanine, and dehydrobutyrine.
