Sequence motifs in promoter regions of BsaN/BicA-regulated genes. A. The sequence motif for the BsaN box as indicated in bold, capital letters was identified using the bioinformatics tool MEME. B. The sequence of the BsaN box generated by MEME from the 5 BsaN-activating promoters as denoted in capital letters. The 3’capitalized letters denote the start of transcription with the exception of PtssM, which is the translational start codon of TssM.
