Three phosphatase families form a community: The phosphohydrolases that act upon inositol pyrophosphates

FEBS Letters, EarlyView.
Inositol pyrophosphates are energy‐rich signaling molecules that perform critical functions in cells. Three different families of phosphatases hydrolyze the β phosphate of the inositol pyrophosphate molecules: two have narrow specificities and one is promiscuous.

Thermal degradation of polymer - fire retardant mixtures. Part VII: Products of degradation and mechanism of fire retardance in polystirene - chloroparaffin mixtures [PDF]

, 1985
The composition of the products formed by the thermal degradation of PS is modified by the presence of a fire retardant chloroparaffin. In particular, chain fragments with more than one phenyl group are evolved in larger yield from polystyrene in the ...

Modelling stem cell differentiation related processes—A practical overview for biologists

FEBS Letters, EarlyView.
Stem cell differentiation is complex and difficult to control experimentally. This review introduces suitable computational modelling approaches that can support stem cell research, from mechanistic ODE and abstract models to multiscale and deep learning methods.

Molecular weight changes and polymeric matrix changes correlated with the formation of degradation products in biodegraded polyethylene [PDF]

, 1999
The molecular weight changes in abiotically and biotically degraded LDPE and LDPE modified with starch and/or prooxidant were compared with the formation of degradation products, The samples were thermooxidized for 6 days at 100 degrees C to initiate ...

Degradation Mechanism of Aflatoxin M₁ by Recombinant Catalase from Bacillus pumilusE-1-1-1: Food Applications in Milk and Beer

Foods
A bacteria capable of degrading aflatoxin M1 (AFM1) was isolated from African elephant manure. It was identified as Bacillus pumilus by 16s rDNA sequencing and named B. pumilusE-1-1-1.

ABL kinase‐dependent phosphorylation of SH proteins promotes their direct interaction with CRK family SH2 domains

FEBS Letters, EarlyView.
CT10 regulator of kinase (CRK) and CRK‐Like (CRKL) are signaling adaptors driving cell adhesion, motility, differentiation, and proliferation. SH2‐domain containing (SH) proteins are enriched in YXXP motifs which when phosphorylated create preferred binding sites for CRK family SH2 domains.

CATALYTIC DEGRADATION OF POLYMERS .2. DEGRADATION OF POLYETHYLENE [PDF]

, 1989
Silica, alumina, silica-aluminas, and zeolites were screened as catalysts for polyethylene degradation in the range 200-600°C. More than 50% of the products in the distillate from the catalytic reactions at T≥400°C, for the more efficient catalysts, were

Reconstructing enzyme evolution by protein engineering

FEBS Letters, EarlyView.
Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...
