Abstract:: ... Analysis of the genome sequence of Streptomyces sp. KCB13F003 showed the presence of a cryptic gene cluster encoding flavin-dependent halogenase and nonribosomal peptide synthetase. Pleiotropic approaches using multiple culture media followed by LC-MS-guided isolation and spectroscopic analysis enabled the identification of two new chlorinated cyclic hexapeptides, ulleungmycins A and B (1 and 2). ...

Subject:: Gram-positive bacteria; Staphylococcus aureus; Streptomyces; acetone; amino acids; antibacterial properties; antibiotic resistance; derivatization; linkage groups; lipopeptides; liquid chromatography; mass spectrometry; methicillin; nuclear magnetic resonance spectroscopy; Korean Peninsula
Abstract:: ... Three cyclic lipopeptides, including one known (1) and two new (2 and 3) compounds, that possess the rare enamide linkage group were discovered from Streptomyces sp. KCB14A132, an actinobacterium isolated from a soil sample collected from Jeung Island, Korea. The NMR and MS-based characterization showed that they differed in the amino acid residues in the peptide backbone. Application of Marfey’s ...

Subject:: Leishmania infantum; Melipona scutellaris; Paenibacillus larvae; Staphylococcus aureus; Streptomyces; amino acids; anti-infective agents; entomopathogens; microorganisms; nuclear magnetic resonance spectroscopy; pollinators; social insects; stingless bees
Abstract:: ... Social insects establish complex interactions with microorganisms, some of which play defensive roles in colony protection. The important role of pollinators such as the stingless bee Melipona scutellaris in nature encouraged us to pursue efforts to study its associated microbiota. Here we describe the discovery of two novel cyclic hexadepsipeptides, meliponamycin A (1) and meliponamycin B (2), fr ...
