FIG 4 .

Predicted secondary structure of novel RNase III sites. Dark triangles indicate the cleavage site identified by 5′ RACE. Open triangles indicate the putative location of the corresponding cut required to leave 2-nt overhangs, characteristic of RNase III cleavage. Colored sections highlight other known regulatory elements such as promoters and structures involved in transcriptional attenuation. The orientation of surrounding genes and the location of an RNase III cleavage site are depicted below the structure.
