Multiple DNA sequence alignment of consensus binding sites of PenR, PntR, and SAV_2989 proteins. (A) Target DNA sequences of PenR and PntR and that predicted for the orthologous SAV_2989 protein from S. avermitilis, generated using Multalin (http://multalin.toulouse.inra.fr/multalin/multalin.html), showing GATCs in a dotted square (i.e., the Sau3AI sites): the CAT in a dotted square indicates the start codon of reverse gene penR, and the CAC in a dotted square indicates the start codon of the reverse gene pntR. The CTTATATAAG sequence with arrows indicates an inverted repeat. (B) Consensus DNA sequence logo (WebLogo [http://weblogo.berkeley.edu/logo.cgi]).
