    Corynebacterium glutamicum genome codes for 7 sigma subunits (factors) of RNA polymerase (RNAP). Each sigma factor is responsible for recognizing promoters of genes belonging to a regulon (sigmulon) involved in specific functions of the cell. Promoters of individual classes recognized by different sigma factors are compiled and the respective consensus sequences of their key recognition motifs (-35 and -10 regions) are derived. In a number of genes, two or more promoters controlled by the same or different sigma factors were discovered. These multiple, overlapping or dual promoters contribute to a complex gene transcription control mechanisms that integrate internal and external signals and tune gene expression in cells as required by environmental and physiological conditions
