FscRI binding sites within the S. albus S4 antimycin gene cluster. The top panel shows experimentally verified FscRI binding sites upstream of genes within the candicidin biosynthetic gene cluster (fscA, fscB1, fscB2, fscD, and fscMI) and putative FscRI binding sites upstream of antB and antC within the ant biosynthetic gene cluster. The middle panel displays the WebLogo (61) for the verified and putative FscRI binding sites above, and the bottom panel shows the relative locations of FscRI binding sites (as red boxes) upstream of antB and antC.
