Transcription factors modulate expression primarily through specific recognition of cognate sequences resident in the promoter region of target genes. AraR (Bacillus subtilis) is a repressor of genes involved in L-arabinose metabolism. It binds to eight different operators present in five different promoters with distinct affinities through a DNA binding domain at the N-terminus ...
