Discovery, mode of action and secretion of Burkholderia sensu lato key antimicrobial specialised metabolites

Burkholderia sensu lato bacteria have genomes rich in biosynthetic gene clusters (BGCs) encoding for multiple bioactive specialised metabolites. Diverse classes of antimicrobial natural products have been isolated from Burkholderia, including polyynes, shikimate pathway derivatives, polyketides, non-ribosomal peptides and hybrid polyketide non-ribosomal peptides. We highlight examples of Burkholderia metabolites, overviewing their biosynthesis, bioactivity, mechanisms of action and secretion.
