Characteristics of transcription start sites in S. pyogenes. a Classification of TSS according to their position relative to CDS; b Consensus sequence for S. pyogenes promoters: motif search reveals extended Pribnow or − 10 boxes and less conserved − 35 boxes, typical of sigma70 dependent promoters, upstream of 885/892 S. pyogenes TSSs. The consensus sequence was generated by using WebLogo (http://weblogo.berkeley.edu/logo.cgi). The mean distances between the − 10 box and the TSS (d1) and between the − 10 and − 35 boxes (d2) were calculated between the 3′ end nucleotide of the − 10 box and the TSS and between the 3′ nucleotide of the − 35 box and the 5′ nucleotide of the − 10 sequence; c Comparison of the 50 nt long sequences upstream of TSS between strains belonging to different emm lineages (the emm type is indicated between brackets). The number of 100% identical sequences is indicated by blue bars while sequences showing polymorphisms are indicated by orange bars
