Phosphorylated cofilin-2 is more prone to oxidative modifications on Cys39 and favors amyloid fibril formation

Redox Biology, 2020
Cofilins are small protein of the actin depolymerizing family. Actin polymerization/depolymerization is central to a number of critical cellular physiological tasks making cofilin a key protein for several physiological functions of the cell.

The Catalytic Activity of Some Mixed Oxides for Depolymerization of Paraldehyde [PDF]

Bulletin of the Chemical Society of Japan, 1974
Abstract Depolymerization of paraldehyde in benzene catalyzed by SiO2–ZrO2, SiO2–TiO2, Al2O3–ZrO2, TiO2–ZrO2, Al2O3–TiO2 (calcined at various temperatures) has been studied. It is observed that in all the cases the catalytic activity (first order rate constant, k) exhibited a maximum against the temperature of heat treatment of the ...

Carboranyl‐Curcuminoids for the Neutron Capture‐Based Treatment of Amyloid Aggregates in Alzheimer's Disease

Advanced Science, EarlyView.
The 10B‐enriched monocarbonyl analog of curcumin (BMAC) 10B‐9 enables site‐specific Boron Neutron Capture Therapy (BNCT) on amyloid‐β (Aβ) fibrils. Neutron irradiation induces histidine oxidation and fibril destabilization, as revealed by 1H‐NMR and FESEM analyses.

Highly Efficient Lignin Depolymerization via Effective Inhibition of Condensation during Polyoxometalate-Mediated Oxidation

, 2019
Depolymerization of lignin to low-molecular-weight products plays a vital role in upgrading of lignin into high-value chemicals. One of the problems of lignin depolymerization is the recondensation of the lignin fragments through positive α carbon (Cα ...

Dual Cytoplasmic and Chloroplastic Mechanisms Fine‐Tune Chloroplast Division through ARC3 Protein Stability

Advanced Science, EarlyView.
ARC3 levels are controlled by cytosolic and chloroplast proteolytic systems. PUB52 mediates ARC3 precursor ubiquitination and degradation in the cytosol, while CLPC1 promotes ARC3 degradation in chloroplasts, where ARC2 protects ARC3 from excessive breakdown. Disrupting these components causes chloroplast division defects, placing them upstream of ARC3.

Lignin Depolymerization with Phenol via Redistribution Mechanism in Ionic Liquids

, 2016
Nowadays, ionic liquids (ILs) have been recognized as a promising way to fractionate biomass. In this study, we discuss how lignin depolymerization was achieved via the redistribution mechanism with phenols in ionic liquids.
