title: Identification of a cyclase gene dictating the C-9 stereochemistry of anthracyclines from Streptomyces nogalater.
abstract: 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 snoaL, encoding a nogalonic acid methyl ester cyclase for nogalamycin, was used to generate nogalamycinone, demonstrating that the single cyclase dictates the C-9 stereochemistry of anthracyclines.
