RESUMO
The complete nucleotide sequence of the linear plasmid pBD2 from Rhodococcus erythropolis BD2 comprises 210,205 bp. Sequence analyses of pBD2 revealed 212 putative open reading frames (ORFs), 97 of which had an annotatable function. These ORFs could be assigned to six functional groups: plasmid replication and maintenance, transport and metalloresistance, catabolism, transposition, regulation, and protein modification. Many of the transposon-related sequences were found to flank the isopropylbenzene pathway genes. This finding together with the significant sequence similarities of the ipb genes to genes of the linear plasmid-encoded biphenyl pathway in other rhodococci suggests that the ipb genes were acquired via transposition events and subsequently distributed among the rhodococci via horizontal transfer.
