Fig. 3.
Heatmap representations of the precision scores Si and Ssum levels estimated by the computer simulation of 13C-MFA using 66 mixtures of non-labeled, [1-13C], and [U-13C]glucose as carbon sources. (a) Comparison of Ssum levels determined for the five metabolic flux distributions. (b) Precision scores Si of each reaction determined for the metabolic flux distribution A (a continuous culture of E. coli MG1655). The red and blue colors in the boxes represent larger (better precision) and smaller (poorer precision) Ssum levels of flux estimation, respectively. (For interpretation of the references to color in this figure legend, the reader is referred to the web version of this article.)
