Circular genome map of E. coli EC1390. The scales indicate the location in Mbp (chromosome) or Kbp (plasmid), starting with the initial coding region. From the innermost circles, circle (1) shows the GC skew (G-C/G + C). The value is plotted as the deviation from the average GC skew of the entire sequence. Circle (2) shows the GC content, plotted using a sliding window. Circle (3, 4) illustrate the coding sequences, 3 is backward strand, 4 is forward strand. The region containing multiple drug resistance genes on pEC1390-1 was indicated
