Scheme of the biosynthetic pathway of myo-inositol and the metabolic regulation strategy in Synechocystis. The genetic modifications made in this study were highlighted. The conversion of glucose-6-phosphate (G-6-P) to myo-inositol (MI) was catalyzed by inositol-1-phosphate synthase (INO1) and myo-inositol-1-monophosphatase (Sll1329 and Sll1383). The phosphoglucose isomerase (Pgi), phosphofructokinase (PfkA), and glucose-6-phosphate dehydrogenase (Zwf) were downregulated by a small RNA tool to direct G-6-P to MI biosynthesis.
