Sequence determinants of RNA G‐quadruplex unfolding by Arg‐rich regions

open access: yesFEBS Letters, EarlyView.
We show that Arg‐rich peptides selectively unfold RNA G‐quadruplexes, but not RNA stem‐loops or DNA/RNA duplexes. This length‐dependent activity is inhibited by acidic residues and is conserved among SR and SR‐related proteins (SRSF1, SRSF3, SRSF9, U1‐70K, and U2AF1).

The wine microbial consortium: a real terroir characteristic

open access: yesOENO One, 2006
Yeast, bacteria, species and strains play a key role in the winemaking process by producing metabolites, which determine wine sensorial qualities. Therefore microbial population enumeration, species identification and strain discrimination from berry ...

Evolution-guided functional analyses reveal diverse antiviral specificities encoded by IFIT1 genes in mammals. [PDF]

open access: yes, 2016
IFIT (interferon-induced with tetratricopeptide repeats) proteins are critical mediators of mammalian innate antiviral immunity. Mouse IFIT1 selectively inhibits viruses that lack 2'O-methylation of their mRNA 5' caps.

Structural instability impairs function of the UDP‐xylose synthase 1 Ile181Asn variant associated with short‐stature genetic syndrome in humans

open access: yesFEBS Letters, EarlyView.
The Ile181Asn variant of human UDP‐xylose synthase (hUXS1), associated with a short‐stature genetic syndrome, has previously been reported as inactive. Our findings demonstrate that Ile181Asn‐hUXS1 retains catalytic activity similar to the wild‐type but exhibits reduced stability, a looser oligomeric state, and an increased tendency to precipitate ...

Genotypic and phenotypic characteristics of Cronobacter species, with particular attention to the newly reclassified species C. helveticus, C. pulveris, and C. zurichensis [forthcoming] [PDF]

open access: yes, 2014
In 2013, Enterobacter helveticus, E. pulveris and E. turicensis, were reclassified as Cronobacter helveticus, C. pulveris and C. zurichensis, respectively. Previously these species had been used as negative controls for some Cronobacter detection assays.

The (Glg)ABCs of cyanobacteria: modelling of glycogen synthesis and functional divergence of glycogen synthases in Synechocystis sp. PCC 6803

open access: yesFEBS Letters, EarlyView.
We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.

THE BASIC FUNCTIONS OF SOUND SIGNALS IN MAMMALS

open access: yesRUDN Journal of Ecology and Life Safety, 2016
All the diversity of sound signals by mammals is subordinated two basic functions: function implementation of the populations of genotype and function realization of the ecological niche of species populations. The basic functions have resulted from some

First Report of Blood Fluke Pathogens with Potential Risk for Emerging Yellowtail Kingfish (Seriola lalandi) Aquaculture on the Chilean Coast, with Descriptions of Two New Species of Paradeontacylix (Aporocotylidae)

open access: yesPathogens, 2021
Blood flukes are digeneans that infect wild and farmed fish that can cause a severe and potentially lethal disease in farmed fish. These parasites are undetectable in the larval stage based on macroscopic observations in the definitive host with the ...

Structural biology of ferritin nanocages

open access: yesFEBS Letters, EarlyView.
Ferritin is a conserved iron‐storage protein that sequesters iron as a ferric mineral core within a nanocage, protecting cells from oxidative damage and maintaining iron homeostasis. This review discusses ferritin biology, structure, and function, and highlights recent cryo‐EM studies revealing mechanisms of ferritinophagy, cellular iron uptake, and ...
