  • Title: Janthinocins A, B and C, novel peptide lactone antibiotics produced by Janthinobacterium lividum. II. Structure elucidation.
    Author: Johnson JH, Tymiak AA, Bolgar MS.
    Journal: J Antibiot (Tokyo); 1990 Aug; 43(8):920-30. PubMed ID: 2211360.
    Abstract:
    The structures of janthinocins A, B and C, three novel macrocyclic peptide lactone antibiotics isolated from fermentations of Janthinobacterium lividum, were determined. The janthinocins are of particular interest because they contain three amino acid residues that have not previously been reported in natural products: Each contains erythro-beta-hydroxy-D-leucine while janthinocins A and B also contain beta-hydroxytryptophan and beta-ketotryptophan, respectively.
