Alignment of promoter regions from the completely SigD-dependent in vivo promoters shown in Fig. 1 plus the experimentally defined SigD-dependent promoter of M. smegmatis (Ms-sigD). A strong consensus sequence in the −35 region is evident (bold letters), and an AT-rich −10 element is also present (underlined). Below the consensus line, the iniB P2 promoter, which is partially SigD dependent, is shown.
