Identification of a transposable genomic island of Paracoccus pantotrophus DSM 11072 by its transposition to a novel entrapment vector pMMB2.

The article reports on the novel entrapment vector, pMMB2, which was used in identifying the a big transposable element, of Paracoccus pantotrophus DSM 11072, TnPpa1 (44.3 kb), which is having a composite structure of diverging oriented replications of a cryptic transposon, Tn3434 (Tn3 family), situated at both ends. Study of the TnPpa1 distribution in P. pantotrophus showed that it is present inside DSM 11072, suggesting its acquisition by lateral transfer.
