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

FEBS 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).

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

FEBS 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 ...

Scientific Opinion on the safety and efficacy of iron compounds (E1) as feed additives for all animal species: ferrous carbonate based on a dossier submitted by Ankerpoort N.V.

EFSA Journal, 2015
Iron from iron‐containing additives is safe in feed up to a maximum content of 250 mg/day for piglets up to one week before weaning, 450 mg/kg for bovines and poultry, 500 mg/kg for ovines, 600 mg/kg for pets and 750 mg/kg for other species/categories ...

Modification of the terms of authorisation of zinc‐l‐selenomethionine as a feed additive for all animal species (Zinpro Animal Nutrition (Europe), Inc.)

EFSA Journal, 2023
Following a request from the European Commission, EFSA was asked to deliver a scientific opinion on the safety and efficacy of a new preparation of zinc‐l‐selenomethionine, with selenium content of 4%, as a nutritional feed additive for all animal ...

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

FEBS 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.

Calpain small subunit homodimerization is robust and calcium‐independent

FEBS Letters, EarlyView.
Calpains dimerize via penta‐EF‐hand (PEF) domains. Using single‐molecule force spectroscopy, we measured the strength and kinetics of PEF–PEF homodimer binding. The interaction is robust, shows a transient conformational step before dissociation, and remains largely insensitive to Ca2+.
