Streptomycesspecies and otherActinobacteriaare ubiquitous in diverse environments worldwide and are the source of, or inspiration for, the majority of antibiotics. The genomic era has enhanced biosynthetic understanding of these valuable chemical entities and has also provided a window into the diversity and distribution of natural product biosynthetic gene clusters. Antimycin is an inhibitor of mitochondrial cytochrome c reductase and more recently was shown to inhibit Bcl-2/Bcl-XL-related anti-apoptotic proteins commonly overproduced by cancerous cells. Here we identify 73 putative antimycin biosynthetic gene clusters (BGCs) in publicly available genome sequences ofActinobacteriaand classify them based on the presence or absence of cluster-situated genesantPandantQ, which encode a kynureninase and a phosphopantetheinyl transferase (PPTase), respectively. The majority of BGCs possess either bothantPandantQ(L-form) or neither (S-form), while a minority of them lack eitherantPorantQ(IQ- or IP-form, respectively). We also evaluate the biogeographical distribution and phylogenetic relationships of antimycin producers and BGCs. We show that antimycin BGCs occur on five of the seven continents and are frequently isolated from plants and other higher organisms. We also provide evidence for two distinct phylogenetic clades of antimycin producers and gene clusters, which delineate S-form from L- and I-form BGCs. Finally, our findings suggest that the ancestral antimycin producer harboured an L-form gene cluster which was primarily propagated by vertical transmission and subsequently diversified into S-, IQ- and IP-form biosynthetic pathways.
