  • Analysis using RAST and MASH identified unique gene regions and 48 natural-product gene clusters, highlighting 10 genes likely responsible for bulgecin A biosynthesis.

Article Abstract

We have produced draft whole-genome sequences for two bacterial strains reported to produce the bulgecins as well as NRPS-derived monobactam β-lactam antibiotics. We propose classification of ATCC 31363 as Paraburkholderia acidophila. We further reaffirm that ATCC 31433 (Burkholderia ubonensis subsp. mesacidophila) is a taxonomically distinct producer of bulgecins with notable gene regions shared with Paraburkholderia acidophila. We use RAST multiple-gene comparison and MASH distancing with published genomes to order the draft contigs and identify unique gene regions for characterization. Forty-eight natural-product gene clusters are presented from PATRIC (RASTtk) and antiSMASH annotations. We present evidence that the 10 genes that follow the sulfazecin and isosulfazecin pathways in both species are likely involved in bulgecin A biosynthesis.

The evolutionary relationships among species of the family were examined based on 255 available genomes representing >85 % of the species from this family. In a phylogenetic tree based on concatenated sequences of 118 core proteins, most species of the genus grouped within one large cluster which also included members of the genera and . Within this large cluster 18-30 clades/subclades of species of the genus consisting of between 1 and 36 species, were observed.

The bulgecins are iminosaccharide secondary metabolites of the Gram-negative bacterium Paraburkholderia acidophila and inhibitors of lytic transglycosylases of bacterial cell-wall biosynthesis and remodeling. The activities of the bulgecins are intimately intertwined with the mechanism of a cobiosynthesized β-lactam antibiotic. β-Lactams inhibit the penicillin-binding proteins, enzymes also critical to cell-wall biosynthesis.
