Fig. 3From: New insights into paulomycin biosynthesis pathway in Streptomyces albus J1074 and generation of novel derivatives by combinatorial biosynthesisCharacterization of regulatory genes. UPLC chromatograms, monitored at 244 nm, of S. albus J1074 and SAM5322 and SAM5342 mutant strains. All extracts were generated by culturing mutant strains in R5A liquid medium during 96 h. Labeled peaks correspond to paulomycin A (1), paulomycin B (2), paulomenol A (4) and paulomenol B (5)Back to article page
