ABSTRACT:
Macrolactams are made by feeding aromatic amino acids as replacement starter units to a mutant strain of the geldanamycin-producing microorganismStreptomyces hygroscopicusvar.geldanusNRRL 3602, wherein the gene cluster encoding enzymes for the biosynthesis of the natural starter unit 3-amino-5-hydroxybenzoic acid has been deleted.
