Table VII. Comparison of malic enzyme with other fluxes in other seeds and plant cells.

The flux through plastidic malic enzyme [mep] or total malic enzyme [metot] was compared with other fluxes as a percentage (e.g. 100 × [plastidic malic enzyme flux/plastidic pyruvate biosynthesis]). [fa], Fatty acid biosynthesis; [gln_upt], Gln uptake; [pyrp], plastidic pyruvate biosynthesis. Fluxes for calculated ratios were extracted from the literature as described in the footnotes.
