The RoxS sequences are boxed in blue. Likely −35 and extended −10 sequences are boxed in mauve and the ResD and Rex binding sites are boxed in green and pink, respectively. The consensus binding sequences for B. subtilis and S. aureus Rex are indicated (Härtig and Jahn, 2012; Pagels et al., 2010). Positions showing 100% conservation are indicated by asterisks. Abbreviations are as follows: Sepi, S. epidermis; SauCol, S. aureus Colindale strain; Shae, S. haemophilus; Ban, B. anthracis; SauNew, S. aureus Newman strain; Bli, B. lichiniformis; Bpu, B. pumilus; Bsub, B. subtilis.
