Biosynthesis of the uridine-derived nucleoside antibiotic A-94964: identification and characterization of the biosynthetic gene cluster provide insight into the biosynthetic pathway

The natural product A-94964 is a uridine-derived nucleoside antibiotic isolated from Streptomyces sp. SANK 60404. In this study, we propose a biosynthetic pathway for A-94964 using gene deletion experiments coupled with in silico analysis of the biosynthetic gene cluster. This study provides insights into the unique biosynthetic pathway for A-94964.
