Table 1 Global regulators. The numbers in braces denote the percentage of genes in the category regulated by the TF. In bold are the functional categories, which are dominantly regulated by the respective TF. Functional categories are as follows: AA, Amino acid biosynthesis; CPRO, Cellular processes; CEN, Cell envelope; CIM, Central intermediary metabolism; DNA, DNA metabolism; ENER, Energy metabolism; FATE, Protein fate; MOB, Mobile and extrachromosomal element functions; Signal, Signal transduction; PUR, Purines, pyrimidines, nucleosides and nucleotides; REG; Regulatory functions; Transport, Transport and binding proteins.
