The structures of brevibacillins and the predicted biosynthetic gene cluster. (A) The non-ribosomal peptide synthetase genes harbored by the Brevibacillus laterosporus DSM 25 genome. (B) The catalytic domains encoded by the gene cluster and the substrates incorporated by the respective modules. Domains: A, adenylation; KR, ketoreductase; T, thiolation; C, condensation; E, epimerization; TD, terminal reductase; TE, thioesterase. (C) Structures of brevibacillins. The red rectangles indicate the more hydrophobic amino acid residues of brevibacillin V, brevibacillin, and brevibacillin I relative to brevibacillin 2V.
