Bogorols and succilins produced by B. laterosporus MG64. (A) Gene cluster of bogorols harbored by B. laterosporus MG64. Green, core biosynthetic gene; blue, transport-related gene; gray, unknown gene; red, additional biosynthetic gene. (B) Structures of bogorols and succilins characterized by LC-MS/MS and NMR. Amino acid residues at positions 3 to 5 (red shaded) of different peptides are shown in the table below the structures. (C) Two-dimensional (2D) NMR correlations (red, ¹H-¹H TOCSY; blue, ¹H-¹H NOESY) confirming succinylation at the third amino acid residue (Lys) of succilin K (see also Fig. S3 in the supplemental material).
