Figure 8From: Role of sgcR3 in positive regulation of enediyne antibiotic C-1027 production of Streptomyces globisporus C-1027Hypothetical schematic regulatory hierarchy of C-1027 biosynthesis in S. globisporus C-1027. Break line box with interrogation point represents unknown pathway-specific regulatory genes and break line arrow represents hypothetic feedback regulation. (+) indicates positive regulation and (?) indicates unknown possible regulation.Back to article page
