Transcriptionally controlled reactions in glycolysis and around the FPP branch point. (A) Three glycolytic reactions are considered to be transcriptionally controlled in all four conditions. The color indicates up- or down- regulation between two conditions, in flux and in expression. Only the reactions that are considered as transcriptionally controlled are shown. White color means that there was no significant change between the two conditions in that particular comparison. The four comparisons that were made was Anaerobic – Aerobic under nitrogen limitation (upper left corner), Anaerobic – Aerobic under carbon limitation (lower left corner), C-limited – N-limited under anaerobic conditions (upper right corner) and C-limited – N-limited under aerobic conditions (lower right corner). (B) Transcriptionally controlled reactions in the ergosterol biosynthesis pathway.
