The crystal structure of the gene product of At3g21360 from Arabidopsis thaliana was determined by the single-wavelength anomalous dispersion method and refined to an R factor of 19.3% (Rfree = 24.1%) at 2.4 A resolution. The crystal structure includes two monomers in the asymmetric unit that differ in the conformation of a flexible domain that spans residues 178-230. The crystal structure confirmed that At3g21360 encodes a protein belonging to the clavaminate synthase-like superfamily of iron(II) and 2-oxoglutarate-dependent enzymes. The metal-binding site was defined and is similar to the iron(II) binding sites found in other members of the superfamily.

The swift rise of hazardous dye effluent from diverse sectors continues to be a severe public health problem and a top priority for environmental preservation, presenting a significant obstacle to the current conventional water treatment systems. This study aims to develop an efficient and reusable approach for removing cresyl fast violet dye using mullite nanoparticles. Some factors such as pH, nano-mullite dosage, agitation speed, time, and others that affect the removal process were studied.

Multilayered van der Waals (vdW) materials are semiconductors composed of atomically thin crystal layers, held together by weak vdW forces. They offer unique crystal structures and electronic properties, distinct from conventional semiconductors, making them a promising platform for linear and nonlinear optics. In this context, the large refractive indexes given by highly polarizable transition metals, combined with excitonic resonances and unconventional crystalline structures, provides a toolbox for exploring non-linear physics and strong light-matter interactions with unprecedented opportunities for nanoscale optics.

The translation of cell-derived extracellular vesicles (EVs) into biogenic gene delivery systems is limited by relatively inefficient loading strategies. In this work, the loading of various nucleic acids into small EVs via their spontaneous hybridization with preloaded non-lamellar liquid crystalline lipid nanoparticles (LCNPs), forming hybrid EVs (HEVs) is described. It is demonstrated that LCNPs undergo pH-dependent structural transitions from inverse hexagonal (H) phases at pH 5 to more disordered non-lamellar phases, possibly inverse micellar (L) or sponge (L) phases, at pH 7.

Choline kinase alpha (CHKA) is a central mediator of cell metabolism linked to cancer and immune regulation. Cellular and clinical evaluation of CHKA has been hampered by challenges in the development of drug-like choline kinase inhibitors. Here, we identify CHKA as an unexpected off-target of histone methyltransferase inhibitors using an integrated phenomic approach.

Microwave-assisted enzymatic hydrolysis is an effective method to shorten the preparation time of porous starch. This study aims to investigate the effect of microwave treatment before/during/after enzymatic hydrolysis on the properties of porous starch. The results showed that the physicochemical properties of the porous starch obtained by microwave-assisted enzymatic hydrolysis were improved.
