FIG. 2.

Circular representation of plasmid RA3. All identified ORFs are represented by solid arrows indicating the direction of transcription. Functional gene clusters are highlighted with different shades of grey. The genes which are not obvious parts of the modules are left white. The predicted promoters are marked with thin black arrows. The class I intragenic repetitions in kfrA, korB, and traC and the class II repetitive regions r1/r3 and r1/r2 are represented by white triangles and boxes, respectively. The white oval marks the position of oriT.
