C. Alignment of vcdRP sequences, including the promoter regions from various Vibrio species: V. cholerae (Vch), V. furnissi (Vfu), V. vulnificus (Vvu), V. harveyi (Vha), V. parahaemolyticus (Vpa), V. anguillarum (Van) and V. splendidus (Vsp). The -35 box, -10 box, transcriptional start site (TSS; arrow), the start and stop positions of VcdP (blue box), the highly conserved base-pairing region (four consecutive cytosines) and rho-independent terminator (brackets) are indicated.
