A first global analysis of plasmid encoded proteins in the ACLAME database.
Leplae R, Lima-Mendez G, Toussaint A. Leplae R, et al. Among authors: toussaint a. FEMS Microbiol Rev. 2006 Nov;30(6):980-94. doi: 10.1111/j.1574-6976.2006.00044.x. FEMS Microbiol Rev. 2006. PMID: 17064288 Review.
Many plasmids are mobile genetic elements (MGEs) and, as other members of that group of DNA entities, their genomes display a mosaic and combinatorial structure, making their classification extremely difficult. As other MGEs, plasmids play a major role in horizontal …

ACLAME: a CLAssification of Mobile genetic Elements.
Leplae R, Hebrant A, Wodak SJ, Toussaint A. Leplae R, et al. Among authors: toussaint a. Nucleic Acids Res. 2004 Jan 1;32(Database issue):D45-9. doi: 10.1093/nar/gkh084. Nucleic Acids Res. 2004. PMID: 14681355 Free PMC article.
This first version contains a comprehensive classification of 5069 proteins from 119 DNA bacteriophages into over 400 functional families. This classification was produced automatically using TRIBE-MCL, a graph-theory-based Markov clustering algorithm that uses sequ …

Mobile elements as a combination of functional modules.
Toussaint A, Merlin C. Toussaint A, et al. Plasmid. 2002 Jan;47(1):26-35. doi: 10.1006/plas.2001.1552. Plasmid. 2002. PMID: 11798283 Review.
We propose here a global classification of these and other bacterial and archaeal mobile elements based on their modular structure. ...Such a database would be very helpful. It would, for instance, allow for analyzing the phylogeny of individual blocks within an ele …

Occurrence of Tn4371-related mobile elements and sequences in (chloro)biphenyl-degrading bacteria.
Springael D, Ryngaert A, Merlin C, Toussaint A, Mergeay M. Springael D, et al. Among authors: toussaint a. Appl Environ Microbiol. 2001 Jan;67(1):42-50. doi: 10.1128/AEM.67.1.42-50.2001. Appl Environ Microbiol. 2001. PMID: 11133426 Free PMC article.
Tn4371, a 55-kb transposable element involved in the degradation and biphenyl or 4-chlorobiphenyl identified in Ralstonia eutropha A5, displays a modular structure including a phage-like integrase gene (int), a Pseudomonas-like (chloro)biphenyl catabol …

Toussaint A, Chandler M. Toussaint A, et al. Methods Mol Biol. 2012;804:57-80. doi: 10.1007/978-1-61779-361-5_4. Methods Mol Biol. 2012. PMID: 22144148 Review.
The importance of horizontal/lateral gene transfer (LGT) in shaping the genomes of prokaryotic organisms has been recognized in recent years as a result of analysis of the increasing number of available genome sequences. ...In this review we summarize the nature and activi …

Transposable phages, DNA reorganization and transfer.
Toussaint A, Rice PA. Toussaint A, et al. Curr Opin Microbiol. 2017 Aug;38:88-94. doi: 10.1016/j.mib.2017.04.009. Epub 2017 May 25. Curr Opin Microbiol. 2017. PMID: 28551392 Review.
As a result of such transposition, a conjugative element (plasmid or genomic island), can either become integrated in the chromosome or receive chromosome segments, which can then be transferred to new hosts by conjugation. In recent years, more and more transposabl …

Stabilization of bacteriophage Mu repressor-operator complexes by the Escherichia coli integration host factor protein.
Gama MJ, Toussaint A, Higgins NP. Gama MJ, et al. Among authors: toussaint a. Mol Microbiol. 1992 Jun;6(12):1715-22. doi: 10.1111/j.1365-2958.1992.tb00896.x. Mol Microbiol. 1992. PMID: 1386646
In this report we show that, consistent with a model in which Mu repressor binding to its operators requires a particular topology of the operator DNA, IHF stimulates repressor binding to the O1 and O2 operators and enhances Mu repression. ...

Instability of bacteriophage Mu transposase and the role of host Hfl protein.
Gama MJ, Toussaint A, Pato ML. Gama MJ, et al. Among authors: toussaint a. Mol Microbiol. 1990 Nov;4(11):1891-7. doi: 10.1111/j.1365-2958.1990.tb02038.x. Mol Microbiol. 1990. PMID: 1964485
Stability of the protein is enhanced in host strains mutated at the hfl locus; however, stability of the transposase activity is not enhanced in these strains, suggesting that functional inactivation of the protein is not simply a result of its proteolysis....
