Identification of a conserved sequence element among the promoters for marR, mprA, and mcbA

(A) Alignment of conserved sequences. Vertical lines indicate nucleotide positions that are identical among all three sequences. Asterisks beneath the mcbA sequence show residues that are identical in mprA and mcbA. (B) Positions of conserved elements in the promoter regions of marR, mprA, and mcbA. Conserved sequences aligned in Panel A are indicated by solid bars.
