Identification of multiple binding sites for the THAP domain of the Galileo transposase in the long terminal inverted-repeats (2013)
Journal Article
Marzo, M., Liu, D., Ruiz, A., & Chalmers, R. (2013). Identification of multiple binding sites for the THAP domain of the Galileo transposase in the long terminal inverted-repeats. Gene, 525(1), https://doi.org/10.1016/j.gene.2013.04.050

Galileo is a DNA transposon responsible for the generation of several chromosomal inversions in Drosophila. In contrast to other members of the P-element superfamily, it has unusually long terminal inverted-repeats (TIRs) that resemble those of Foldb...

Hsmar1 transposition is sensitive to the topology of the transposon donor and the target (2013)
Journal Article
Claeys Bouuaert, C., & Chalmers, R. (2013). Hsmar1 transposition is sensitive to the topology of the transposon donor and the target. PLoS ONE, 8(1), Article 0053690. https://doi.org/10.1371/journal.pone.0053690

Hsmar1 is a member of the Tc1-mariner superfamily of DNA transposons. These elements mobilize within the genome of their host by a cut-and-paste mechanism. We have exploited the in vitro reaction provided by Hsmar1 to investigate the effect of DNA su...

H-NS mediates the dissociation of a refractory protein–DNA complex during Tn10/IS10 transposition (2011)
Journal Article
Liu, D., Haniford, D. B., & Chalmers, R. (2011). H-NS mediates the dissociation of a refractory protein–DNA complex during Tn10/IS10 transposition. Nucleic Acids Research, 39(15), https://doi.org/10.1093/nar/gkr309

Tn10/IS10 transposition takes place in the context of a protein–DNA complex called a transpososome. During the reaction, the transpososome undergoes several conformational changes. The host proteins IHF and H-NS, which also are global regulators of g... Read More about H-NS mediates the dissociation of a refractory protein–DNA complex during Tn10/IS10 transposition.

The transposon-like correia elements encode numerous strong promoters and provide a potential new mechanism for phase variation in the meningococcus (2011)
Journal Article
Siddique, A., Buisine, N., & Chalmers, R. (2011). The transposon-like correia elements encode numerous strong promoters and provide a potential new mechanism for phase variation in the meningococcus. PLoS Genetics, 7(1), Article 13. https://doi.org/10.1371/journal.pgen.1001277

Neisseria meningitidis is the primary causative agent of bacterial meningitis. The genome is rich in repetitive DNA and almost 2% is occupied by a diminutive transposon called the Correia element. Here we report a bioinformatic analysis defining eigh...

Base flipping in Tn10 transposition: an active flip and capture mechanism (2009)
Journal Article
Bischerour, J., & Chalmers, R. (2009). Base flipping in Tn10 transposition: an active flip and capture mechanism. PLoS ONE, 4(7), Article e6201. https://doi.org/10.1371/journal.pone.0006201

The bacterial Tn5 and Tn10 transposases have a single active site that cuts both strands of DNA at their respective transposon ends. This is achieved using a hairpin intermediate that requires the DNA to change conformation during the reaction. In Tn...
