Summary

genomes regardless of phylogenetic or geographical dispersal. The post-translationally modified peptidic product encoded by this BGC─which was accessed via heterologous production and its structure elucidated using a combination of mass spectrometry and NMR spectroscopy─was found to be a copper chelator. Similar BGCs were then found in genomes of other marine bacterial genera coinhabiting the microbiomes of sponges and corals. The phylogenomic workflows described herein were implemented in a pedagogic setting at the Georgia Institute of Technology to provide hands-on instruction to undergraduate students in bacterial phylogeny, genome mining, and natural product chemistry.
