Mol Genet Genomics . 2001 Oct; 266(2):276-88. PMID: 11683270
Fragments spanning 20 kb of Streptomyces nogalater genomic DNA were characterized to elucidate the molecular genetic basis of the biosynthetic pathway of the anthracycline antibiotic nogalamycin. Structural analysis of the...

Antimicrob Agents Chemother . 2000 Jan; 44(2):396-9. PMID: 10639368
Nogalamycin is an anthracycline antibiotic produced by Streptomyces nogalater. Its aglycone has a unique stereochemistry (7S, 9S, 10R) compared to that of most other anthracyclines (7S, 9R, 10R). The gene...

Metsa-Ketela M, Salo V, Halo L, Hautala A, Hakala J, Mantsala P, et al.
FEMS Microbiol Lett . 1999 Nov; 180(1):1-6. PMID: 10547437
Degenerated oligonucleotide primers were designed to amplify fragments of ketosynthase genes from polyketide antibiotics producing Streptomyces spp. and bacterial strains enriched from soil samples. Cell lysates were used as templates...

Bioorg Med Chem Lett . 1999 Oct; 9(18):2639-42. PMID: 10509907
Compounds produced by the polyketide ketoreductase deficient Streptomyces mutants HO61 and P67 are described. The structures of the compounds indicate that ketoreductase activity is required for correct condensation of the...

Chem Biol . 1997 Dec; 4(10):751-5. PMID: 9375253
Background: Mithramycin, nogalamycin and aclacinomycins are aromatic polyketide antibiotics that exhibit antitumour activity. The precursors of these antibiotics are formed via a polyketide biosynthetic pathway in which acetate (for mithramycinone...
