  • Title: Biosynthetic studies of aridicin antibiotics. I. Labeling patterns and overall pathways.
    Author: Chung SK, Taylor P, Oh YK, DeBrosse C, Jeffs PW.
    Journal: J Antibiot (Tokyo); 1986 May; 39(5):642-51. PubMed ID: 3733513.
    Abstract:
    Biosynthetic feeding experiments with 14C and 13C-labeled precursors in Kibdelosporangium aridum have established the biosynthetic origins of the heptapeptide aglycone of the aridicin antibiotics, and the tentative sequence of the later stage biosynthetic transformations. The aglycone moiety has been found to be derived from tyrosine, sodium acetate and L-methionine. It is suggested that the preformed aglycone is first mannosylated and then followed by the attachment of the glycolipid. The sugar oxidation to the glucuronic acid level was found to take place as a terminal step of the biosynthesis.
