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 ...

Abstract:
... The advances of genomic sequence analyses and genome mining tools have enabled the exploration of untapped microbial natural products. Through genome mining studies to discover cryptic natural products, we found biosynthetic genes encoding a new lasso peptide in the genome sequence of a soil bacterium, Streptomyces sp. KCB13F003 isolated from Ulleung Island (a small volcanic island), Korea. The pr ...
