Fig. 1From: Redirection of metabolic flux in Shewanella oneidensis MR-1 by CRISPRi and modular design for 5-aminolevulinic acid productionMetabolic pathway and schematic diagram of 5-ALA synthesis from glucose to TCA cycle. Genes shown in red were downregulated using the CRISPRi system, while metabolites represented in yellow were analyzed by HPLC. Two important plasmids for expression of RchemA with GroESL and Glk-GalP were harboring in the genetic MR-1Back to article page
