Features of the Acetobacter pasteurianus 386B chromosome. (A) Circular representation of the annotated chromosome of A. pasteurianus 386B. The circles represent (from the outside to the inside): circle 1, DNA base position (bp); circle 2, protein-coding regions transcribed clockwise; circle 3, protein-coding regions transcribed anti-clockwise; circle 4, G+C content plotted using a 10-kb window in steps of 200 bp; circle 5, GC skew plotted using a 10-kb window in steps of 200 bp. (B) Linear representation of the A. pasteurianus 386B chromosome. The occurrence of the architecture imparting sequences (AIMS) is shown (in green) on both strands of the chromosome. These AIMS consist of the octamers [A|C|G]GGGCAGG, GGGCAGG[G|T], GAGCAGGG, GG[T|C]GAGGG, and GGG[C|A]AGGG. The origin of chromosomal replication (oriC) as well as the replication termination (dif) site are marked with a vertical arrow. The location of five rRNA operons (rrnA-rrnE) on the leading strand of the A. pasteurianus chromosome is indicated with horizontal black arrows.
