Fig. 4From: Carriage of Shiga toxin phage profoundly affects Escherichia coli gene expression and carbon source utilizationStx2a phage-dependent changes geared at reprogramming MG1655 metabolism. A schematic representation of the proposed model for the Stx2a phage-dependent changes in the gene expression, NADH/NAD+ ratio and level of ArcAB phosphorylation leading to profound differences in the carbon source utilization. For more details refer to the text in the discussion. Legend: red arrow pointing down = downregulation/decrease; green arrow pointing up = upregulation/increase, ArcAB-P = phosphorylated ArcABBack to article page
