Figure 1From: Characterization of the iron-regulated desA promoter of Streptomyces pilosus as a system for controlled gene expression in actinomycetesBiosynthesis of desferrioxamine B from lysine. The desferrioxamine B component binds Fe3+ to form ferrioxamine B. Lysine decarboxylase encoded by the desA gene catalyzes the first step of the biosynthetic pathway.Back to article page
