(A) Transcription of the yecM-cutC region as observed in mRNA-seq. cutC appears to be co-transcribed with yecM in all conditions tested. (B) Sequence of micL-cutC genomic region. MicL (chromosome positions 1956771 to 1956462) and MicL-S (chromosome positions 1956544 to 1956462) terminate within the poly(T) stretch of the rho-independent terminator of cutC (stem indicated by arrows). The predicted -10 and -35 σE promoter elements of micL are underlined and the site of cleavage to generate MicL-S is indicated by the vertical arrow. A previous study reported a σE-dependent promoter for cutC at position 1957010 (Dartigalongue et al., 2001). We find no evidence for this site in our tiling array, deep sequencing and Northern data upon σE overexpression.
