BMC Genomics 2005, 6:103 http://www.biomedcentral.com/1471-2164/6/103 FCiigrcuurlear1map of pAW63 Circular map of pAW63. Coding Sequences (CDS) are represented by block arrows on the outer circle. Predicted func- tions/homologies are indicated by the color key featured below; numbers in brackets refer to main CDSs (see Table 1 for details). The first circle from the center delineates the functional modules identified on the plasmid; T indicates the transfer (tra) region, C indicates the control region (replication and regulation), and M indicates the two mobile DNA-associated flank- ing regions. The second circle from the center is a circular bar graph of the G+C composition percentage of the plasmid sequence, with the overall mean value (33.8%) as baseline; values above the line are G+C rich (max value 51% G+C) and values below the line are A+T rich (min value 16% G+C). The third circle from the center is a graduated size scale with small tick marks every 1 kb and large tick marks every 10 kb. Page 3 of 14 (page number not for citation purposes)
