Fig. 3From: Fine tuning the glycolytic flux ratio of EP-bifido pathway for mevalonate production by enhancing glucose-6-phosphate dehydrogenase (Zwf) and CRISPRi suppressing 6-phosphofructose kinase (PfkA) in Escherichia coliSchematic diagram of CRISPRi on pfkA suppression. a Schematic diagram of pfkA transform. b Abridged general view of metabolic flux change after CRISPRi regulation. The red arrow indicated decreased metabolic flux, the green arrow indicated increased metabolic fluxBack to article page
