“…1,2 ) revealed that the aglycone is derived from five acetates, one propionate, one butyrate, and a C2 unit corresponding to carbons 3 and 4 to which a hydroxyl and a methoxy group are attached respectively. However, the biosynthetic origin of the two carbons has remained unknown.…”

“…Well-known members of this class are methymycin, erythromycin, carbomycin, cirramycin, mycinamycin, and spiramycin. The biosynthetic steps leading from lactone to the final product have been delineated for many of these antibiotics (1,3,4,15,22) through the use of blocked mutants and bioconversion of intermediates. Information concerning assembly of the lactone ring, which has been the first isolable biosynthetic intermediate in macrolide synthesis, was obtained by analyzing incorporation of labeled acetate, propionate, and butyrate.…”

“…-Wenn auch diese ersten Abbauversuche nur ein sehr vages Bild der Struktur von Niphimycin I und Copiamycin A geben, beweisen sie doch die sehr nahe strukturelle Venvandtschaft dieser beiden Antibiotica. und geben weitere Hinweise auf ihre Zugehorigkeit zu den Makroliden, denn alle identifizierten Abbauprodukte, insbesondere auch diejenigen rnit mehrfach ver-zweigter Kohlenstoffkette, sind im Einklang rnit einem gemischten Polyketid-Aufbau aus Acetat-und Propionat-Einheiten, der fur die meisten Makrolide so typisch ist [24].…”
