Synechococcus 2973 flux map determined in PBRs and SF and Synechococcus 7942 from the PBR. Syn. 2973 PBR values are listed first, followed by SF in italicized values and the third values are Syn. 7942 PBR. Net fluxes are normalized to net uptake of 100 mol CO₂. Mean flux values and 95% confidence intervals are given in Additional file 1: Tables S3–S5. Estimated net CO₂ uptake rates (mmol/gDCW/h) were 12.2 (PBR), 6.7 (SF), and 5.1 (PBR- 7942). Dotted lines represented pathways with enzymes that are not annotated for Synechococcus elongatus on the KEGG Genome database. ˫ indicates the inhibition of pyruvate kinase by ATP
