From: Detection of prokaryotic promoters from the genomic distribution of hexanucleotide pairs
Genome-derived distribution matrices generated for consensus sequences from transcription factors of three different organisms. (A) E. coli, (B) B. subtilis, and (C) M. tuberculosis. The name of the transcription factor is identified above each matrix. The mismatch number of each cell is indicated on both sides of matrices. The analyzed consensus sequence is shown under each matrix, along with the allowed spacing range. The first row corresponds to principal σ factors, the second row to alternative σ factors, and the third row to transcriptional regulators.
