Structure of plasmid pSfr64a. Descriptions are presented from the innermost circle outward: regions with homology to pRet42a (red), pRet42d (green) and the chromosome of NGR234 (blue); ORFs with homology to pRet42a (red), pRet42d (green) and the chromosome of NGR234 (blue); transposon-related ORFs: pSFR64a_00003, pSFR64a_00009, pSFR64a_00084, pSFR64a_00088 (black arrows); transposon-related ORFs on pRet42a (PA00138) and pRet42d (PD00033, PD00041, PD00093, PD00124, PD00101, PD00123, PD00041) located nearby to the ORFs where similarity is interrupted (purple arrows); GC content (blue, low GC; gray, medium GC; red, high GC); predicted ORFs on the forward and reverse strands in color code (the colors are according to their functional category as follows: orange, amino acid biosynthesis; light red, biosynthesis of cofactors; pale green, macromolecule biosynthesis; mild red, central intermediary metabolism; red, energy transfer; magenta, degradation; pink, structural elements or cell processes; dark gray, transport; bright green, transposon-related functions; sky blue, transcriptional regulators; green, transfer functions or replication functions; brown, hypotheticals; bone, orphans; black, function not determined). The locations of the replication genes (R) and of the transfer region (T) are indicated.
