Occurrence of Tn4371-related mobile elements and sequences in (chloro)biphenyl-degrading bacteria

Article Abstract:

Research indicates that (chloro)biphenyl catabolic gene clusters, or bph genes, occurring on Tn4371, a transposable element in bacterial degradation, are highly conserved between various (chloro)biphenyl-degrading hosts, primarily belonging to the beta-proteobacteria but globally isolated.

The biphenyl- and 4-chlorobiphenyl-catabolic transposon Tn4371, a member of a new family of genomic islands related to IncP and Ti plasmids

Article Abstract:

Research has been conducted on biphenyl catabolic transposon Tn4371. The authors report that they have completed and analyzed nucleotide sequence of this transposon, and that it has a mosaic structure composed of several building blocks.

RP4::Mu3A-mediated in vivo cloning and transfer of a chlorobiphenyl catabolic pathway

Article Abstract:

The catabolic genes that mediate the chlorobiphenyl catabolic pathway was activated by utilizing the plasmid RP4::Mu3A of Burkhoderia sp. JB1 strain. Mobilization of chromosomally located aromatic catabolic pathways by plasmid RP4::Mu3A involves the transposition of the catabolic genes from the transposon. Furthermore, the transfer of Bph+ prime plasmids from the Alcaligenes eutrophus to Escherichia coli led to the metabolism of diphenylmethane and biphenyl.
