Phys Chem Chem Phys
. 2024 Dec;
27(5):2320-2332.
PMID: 39688270
The emergence of very high NMR magnetic fields will certainly encourage the study of larger biological systems with their dynamics and interactions. NMR spin relaxation allows probing the dynamical properties...

Biomolecules
. 2023 Sep;
13(9).
PMID: 37759676
Genome sequencing of the human parasite revealed an interesting gene superfamily, called micro-exon gene (), that encodes secreted MEG proteins. The genes are composed of short exons (3-81 base pairs)...

PLoS One
. 2023 Aug;
18(8):e0289444.
PMID: 37535563
Micro-Exon Genes are a widespread class of genes known for their high variability, widespread in the genome of parasitic trematodes such as Schistosoma mansoni. In this study, we present a...

J Biol Chem
. 2023 Jul;
299(8):105004.
PMID: 37394004
The resistance of gram-negative bacteria to silver ions is mediated by a silver efflux pump, which mainly relies on a tripartite efflux complex SilCBA, a metallochaperone SilF and an intrinsically...

Monneau Y, Arrault C, Duroux C, Martin M, Chirot F, Mac Aleese L, et al.
Phys Chem Chem Phys
. 2023 Jan;
25(4):3061-3071.
PMID: 36617868
Silver has been used for its antimicrobial properties to fight infection for thousands of years. Unfortunately, some Gram-negative bacteria have developed silver resistance causing the death of patients in a...

Nat Commun
. 2021 Oct;
12(1):5862.
PMID: 34615873
NLRP3 controls the secretion of inflammatory cytokines IL-1β/18 and pyroptosis by assembling the inflammasome. Upon coordinated priming and activation stimuli, NLRP3 recruits NEK7 within hetero-oligomers that nucleate ASC and caspase-1...

57(70):8726-8729.
PMID: 34396382
SilE and SilB are both proteins involved in the silver efflux pump found in Gram-negative bacteria such as S. typhimurium. Using model peptides along with NMR and CD experiments, we...
