TN7 transposes from the chromosome of Pseudomonas aeruginosa into the plasmid R68.
45 with tandem IS21, at up to 400 times the frequency that it transposes into R68, which has …

Background Bacterial insertion sequences (IS) of IS200/IS605 and IS607 family often
encode a transposase (TnpA) and a protein of unknown function, TnpB. Results Here we …

ABSTRACT The atzS-atzT-atzU-atzV-atzW gene cluster of the Pseudomonas sp. strain ADP
atrazine-degradative plasmid pADP-1, which carries genes for an outer membrane protein …

Plasmid conjugative transfer systems comprise type IV secretion systems (T4SS) coupled to
DNA processing and replication. The T4SSs are divided into two phylogenetic subfamilies …

Tn10 and Tn9 from temperature-sensitive replicons RPI:: Tn10 Rep is and RP1:: Tn9 Rep ts
and Tn5 from the" suicidal" vector pSUP5011 may integrate in the P. pseudomallei …

Mechanisms of conjugal immunity preventing redundant exchange between two cells
harbouring the same conjugative element have been reported in diverse bacteria. Such a …

Azotobacter vinelandii belongs to the γ subdivision of eubacteria and has one of the highest
respiratory rates. It is considered to be among the probable progenitors of mitochondria …

We show that both flanking IS 256 elements carried by transposon Tn 4001 are capable of
generating head-to-tail tandem copies and free circular forms, implying that both are active …

Perhaps due to my optimistic disposition, I like to think that there is a good reason why every
little thing about Escherichia coli, and other bacteria, is the way it is. That is, I like to believe …

An Escherichia coli strain, ECOR28, was found to have insertions of an identical sequence
(1,279 bp in length) at 10 loci in its genome. This insertion sequence (named IS 621) has …
