FIG. 3.

Primer extension and sequence analysis of the mar-like promoter region. Total RNA was prepared from cells grown in the presence or absence of benzaldehyde and harvested in exponential growth phase. (A) Primer extended products were separated by electrophoresis under denaturing conditions alongside sequencing reactions with the same primer. (B) Promoter sequence. The mapped transcription/translation start site (+1) is in bold. The TBP and TFB binding sites are indicated by boxed regions, and tandem inverted repeats are underlined.
