Putative transcription start sites for ftsZTB. Transcription start sites and the putative −35 and −10 regions in the 5’ flanking region of ftsZTB are shown. E. coli sigma 70 type −35 and −10 boxes, TTagCA and TAcggT, respectively (uppercase - identity with the consensus), identified upstream of the P2 promoter. Because of at least 3 matches to the s70 E. coli consensus, the P2 promoter was included in group A mycobacterial promoters. For promoters P1 and P4, distinct s70 type −35 regions were seen, but no identifiable −10 sequences were found. For promoter P3, no apparent −10 or −35 regions were seen. Therefore, these three promoters could belong to mycobacterial group C promoters and may contain recognition sequences for regulators other than σA or σB (33).
