Figure 4

Promoter region sequence of the cox operon encoding the A-type cytochrome c oxidase.

The putative Shine-Dalgarno sequence and translation start codon are in lower case and italic, respectively. Predicted Fnr-binding sites are in bold while putative RpoS-and PrrA-binding sites are boxed. Putative transcription start site, −10 and −35 boxes for the sigma 70 transcription factor are indicated by a dot and by horizontal bars respectively. Numbers indicate the position relative to the start codon.
