Figure 1.

Comparative gene map of the Sulfolobus self-transmissable plasmids. Thick, black horizontal lines delineate the genomic sections A, B and C. The main conserved open reading frames (ORFs) in section A, the highly conserved ORF153 and ORF196, the integrase and PlrA are labeled for pKEF9. Homologs in the different plasmids can be identified by color and pattern. Open reading frames shown as an empty box have no homologs in the other plasmids. The short regularly spaced repeat (SRSR) clusters are indicated by green rectangular boxes on the linear genomes of pKEF9 and pNOB8-33. Recombination motifs are represented by yellow boxes on the linear genomes. The location of the deletion in pNOB8-33 is downstream from ORF617. The deletion variant plasmid pING2 extends from downstream of ORF1044 to the center of the operon in section C.
