Classifications of TSSs and the features of promoters in M. marinum. a Classification scheme for TSSs based on genome position and TSS strength: primary (P), secondary (S), internal (I), antisense (A) and orphan (O). b Venn diagrams showing classifications of TSSs identified under normoxic (N, black color) and hypoxic (H, red color) conditions. A TSS could be classified into more than one category. c Venn diagram showing the numbers and percentages of pTSSs identified under normoxia and hypoxia. d Consensus for − 10 motif of 1988 promoters upstream of pTSSs expressed under both normoxia and hypoxia generated by MEME [30, 31]. Regions containing 12 bp (− 5 to − 16 relative to TSSs) were used for analysis. e Numbers and percentages of G_− 14 or G_− 13 and TGN preceding the − 10 YANNNT motif
