GAP formation from CO₂ through the canonical Calvin–Benson cycle. The reactions corresponding to the red arrows appear in the S7P-forming transaldolase variant, but not in the S7P-removing transaldolase variant. The reactions corresponding to the orange arrows appear in the S7P-removing transaldolase variant, but not in the S7P-forming transaldolase variant. For abbreviations, the meaning of the numbers before each metabolite, and currency metabolites, please see the legend in Fig. 1. In this paper, the FBP and SBP formation reactions catalyzed by aldolase are named FBP aldolase and SBP aldolase, respectively.
