Structural studies and functional engineering of NanX: an anhydro‐sialic acid transporter from Escherichia coli

FEBS Open Bio, EarlyView.
Biophysical characterisation shows that NanX, a membrane transport protein from the major facilitator superfamily (MFS), forms both monomers and dimers after purification. AlphaFold modelling and substrate docking provide information on residues likely involved in substrate recognition for NanX and another MFS member, NanT.

Applications and Synthesis of Chiral Cyclic Carbonates from Asymmetric CO2 Conversion

The cycloaddition of CO2 to epoxides leading to cyclic carbonates is one of the most investigated strategies for the valorization of CO2 through the production of useful chemicals. While most efforts in this area focus on the development of new catalytic

Avidin is evolutionarily conserved in fish but dispensable for development and resistance against Streptococcus agalactiae in zebrafish

FEBS Open Bio, EarlyView.
The presence of biotin‐binding avidin proteins in fish and their biological significance are poorly characterized. We cataloged fish avidins and demonstrate that they are widely present and evolutionarily conserved. We created avd knockout zebrafish and show that zebavidin is dispensable for development and that resistance of avd knockout embryos in ...

Novel Quantification Method for Lithium Ion Battery Electrolyte Solvents in Aqueous Recycling Samples Using Solid‐Phase Extraction/Gas Chromatography‐Flame Ionization Detection

Advanced Energy & Sustainability Research
Efficient recycling processes of lithium ion batteries are critical for advancing the sustainability of this technology. Yet, the quantitative analysis of potential electrolyte residues in wastewaters generated in the recycling process can be challenging.

Formation of bio-based cyclic carbonates from CO2 and renewable feedstocks via porous poly(azomethine) -based heterogeneous catalysts approach

Journal of CO2 Utilization
Two families of heterogeneous porous catalysts based on iron or cobalt poly(azomethine) (PAM) networks were reported to synthesize cyclic carbonates from bio-based aliphatic oxides epoxides and carbon dioxide (CO2).

Structural and biochemical insights into the thermostable esterase Ta0887 from Thermoplasma acidophilum

FEBS Open Bio, EarlyView.
In this study, a novel esterase from the thermoacidophilic archaeon Thermoplasma acidophilum was biochemically and structurally characterized. Our results demonstrate that Ta0887 is a highly thermostable esterase that preferentially hydrolyzes p‐nitrophenyl hexanoate and possesses an α‐helical cap domain that likely contributes to its substrate ...

A pathway to cyclic carbonates: Cycloaddition of carbon dioxide to epoxidized methyl oleate on grafted heterogeneous catalysts

Journal of CO2 Utilization
The conversion of CO2 into value-added cyclic carbonates via cycloaddition to bio-derived epoxides presents a sustainable approach for CO2 utilization. However, the production of cyclic carbonates from bio-sources such as epoxidized vegetable oils (EVOs)

Electrosynthesis of Cyclic Carbonates From CO2 and Diols in Ionic Liquids Under Mild Conditions

International Journal of Electrochemical Science, 2011
A new electrochemical process for synthesis of cyclic carbonates from CO2 and diols has been tested in CO2-saturated room temperature ionic liquids (RTILs) for the first time.

Reaction of CO2 With Alcohols to Linear-, Cyclic-, and Poly-Carbonates Using CeO2-Based Catalysts

Frontiers in Energy Research, 2020
Reaction of CO2 with alcohols to organic carbonates is one of non-reductive CO2 conversion methods. The catalysts are needed for this reaction, at the same time, effective H2O removal methods are also needed because the yield of organic carbonates is ...

The C‐terminal domain of yeast Arginyltransferase1 is essential for its catalytic activity

FEBS Open Bio, EarlyView.
Arginyltransferase 1 (Ate1), a eukaryotic enzyme, catalyses arginylation, transferring arginine from tRNA‐Arg to the amino terminus of the target protein. Overexpression of Ate1 in yeast is lethal and is dependent on arginylation. This study elucidates how mutations in the cofactor‐binding and active site of Ate1 and truncation of its structural ...
