1.
Bizebard T, Dreyfus M
Methods Mol Biol
. 2015 Jan;
1259:199-209.
PMID: 25579588
Enzymes from cold-adapted organisms are generally endowed with lower activation enthalpies than their counterparts from organisms growing at higher temperatures, making them better catalysts in the cold. However, the enzymes...

Iost I, Bizebard T, Dreyfus M
Biochim Biophys Acta
. 2013 Feb;
1829(8):866-77.
PMID: 23415794
DEAD-box proteins are RNA-dependent ATPases that are widespread in all three kingdoms of life. They are thought to rearrange the structures of RNA or ribonucleoprotein complexes but their exact mechanism...

Mangeol P, Bizebard T, Chiaruttini C, Dreyfus M, Springer M, Bockelmann U
Proc Natl Acad Sci U S A
. 2011 Oct;
108(45):18272-6.
PMID: 22025688
Ribosomal (r-) RNA adopts a well-defined structure within the ribosome, but the role of r-proteins in stabilizing this structure is poorly understood. To address this issue, we use optical tweezers...

Proux F, Dreyfus M, Iost I
Mol Microbiol
. 2011 Aug;
82(2):300-11.
PMID: 21859437
DEAD-box RNA-dependent ATPases are ubiquitous enzymes that participate in nearly all processes involving RNA, but their detailed molecular functions remain generally unknown. SrmB, one of the five Escherichia coli DEAD-box...
5.
Dreyfus M, Heurgue-Hamard V
Mol Microbiol
. 2011 Jan;
79(2):288-91.
PMID: 21219451
In this issue of Molecular Microbiology, Schaub and Hayes report that, compared with other enterobacteria, Escherichia coli K12 carries two mutations - one in the prfB gene encoding the release...

Cartier G, Lorieux F, Allemand F, Dreyfus M, Bizebard T
Biochemistry
. 2010 Feb;
49(12):2636-46.
PMID: 20166751
Spontaneous rearrangements of RNA structures are usually characterized by large activation energies and thus become very slow at low temperatures, yet RNA structure must remain dynamic even in cold-adapted (psychrophilic)...
7.
Banroques J, Doere M, Dreyfus M, Linder P, Tanner N
J Mol Biol
. 2009 Dec;
396(4):949-66.
PMID: 20026132
Motif III in the putative helicases of superfamily 2 is highly conserved in both its sequence and its structural context. It typically consists of the sequence alcohol-alanine-alcohol (S/T-A-S/T). Historically, it...

Trubetskoy D, Proux F, Allemand F, Dreyfus M, Iost I
Nucleic Acids Res
. 2009 Sep;
37(19):6540-9.
PMID: 19734346
DEAD-box proteins play specific roles in remodeling RNA or ribonucleoprotein complexes. Yet, in vitro, they generally behave as nonspecific RNA-dependent ATPases, raising the question of what determines their specificity in...

Dreyfus M
Prog Mol Biol Transl Sci
. 2009 Feb;
85:423-66.
PMID: 19215779
In prokaryotes, translation influences mRNA decay. The breakdown of most Escherichia coli mRNAs is initiated by RNase E, a 5'-dependent endonuclease. Some mRNAs are protected by ribosomes even if these...

Proux F, Dreyfus M
Methods Enzymol
. 2009 Jan;
447:243-58.
PMID: 19161847
In Escherichia coli, synthesis and translation of individual mRNAs are usually synchronous, so that no long ribosome-free mRNA stretch exists between the RNA polymerase and the leading ribosome. By comparing...
