Trimethylation of the R5 Silica-Precipitating Peptide Increases Silica Particle Size by Redirecting Orthosilicate Binding

17 July, 2020 - 00:00

Unexpected direction : The silaffin R5 peptide precipitates silica from solutions of orthosilicic acid. Post-translational modifications in R5 modulate silica morphology. We studied the effect of lysine trimethylation, which installs a positive charge, on silica particle formation. Surprisingly, trimethylation led to larger particle sizes by reducing the maximum activity of R5 and redirecting orthosilicate binding to the R5N terminus.

Probing the Compatibility of an Enzyme-Linked Immunosorbent Assay toward the Reprogramming of Nonribosomal Peptide Synthetase Adenylation Domains

17 July, 2020 - 00:00

A reprogramming platform : An enzyme-linked immunosorbent assay (ELISA) using a combination of small-molecule probes can detect subtle structural changes in the substrate binding pockets of aryl acid adenylation (A) domains. Combined with a directed-evolution approach, the ELISA technology can be used to isolate aryl acid A-domains with the desired activity.

A Hydroxyquinoline-Based Unnatural Amino Acid for the Design of Novel Artificial Metalloenzymes

17 July, 2020 - 00:00

Expanding biotransformations : Several metal-binding noncanonical amino acids have been incorporated into protein scaffolds to create artificial metalloenzymes. We introduced 2-amino-3-(8-hydroxyquinolin-3-yl)propanoic acid (HQAla) into lactococcal multidrug-resistance regulator (LmrR) and complexed it with several transition metal ions such as CuII, ZnII and RhIII to showcase its catalytic potential in a variety of different reactions.

Visible Light-driven Dehydrogenation of Benzylamine under Liberation of H<sub>2</sub>

17 July, 2020 - 00:00

Earth-abundant metal photocatalyst : The photocatalyst Ni/CdS@MIL-101 (MIL-101 green, CdS yellow, Ni grey) dehydrogenates benzylamine via the liberation of H2 (amine splitting). A faster electron transfer from CdS to Ni and a stronger benzylamine binding at the Ni clusters make the earth abundant metal Ni superior in comparison to Pd and Pt.

Identification of Novel Unspecific Peroxygenase Chimeras and Unusual YfeX Axial Heme Ligand by a Versatile High-Throughput GC-MS Approach

17 July, 2020 - 00:00

High-throughput biocatalysis : The developed multiple injections in a single experimental run (MISER) GC-MS technique allows a substrate independent assay for the 96-well plate analysis. Utilisation of this concept yielded novel unspecific peroxygenase chimeras, produced in S. cerevisiae , consisting of subdomains from three different fungal UPO genes for the hydroxylation of tetralin. The GC-technique was additionally applied to evaluate a YfeX library in an E. coli whole-cell system for the carbene-transfer reaction on indole, which revealed an thus far unknown axial heme ligand: tryptophan.

Plasma-Assisted Catalytic Effects of TiO<sub>2</sub>/Macroporous SiO<sub>2</sub> on the Synthesis of Light Hydrocarbons from Methane

17 July, 2020 - 00:00

Valuable light hydrocarbons were successfully synthesized using a plasma-assisted catalytic system. The catalytic activity of titania nanoparticles seemed to selectively increase the conversion of intermediates into longer hydrocarbons, while reducing coke. DFT calculations revealed that the intermediates on titania seemed to prefer to form longer hydrocarbons rather than coke.

Non-conventional Hydrogen Bonding and Aromaticity: A Systematic Study on Model Nucleobases and Their Solvated Clusters

17 July, 2020 - 00:00

Aromaticity modulation with sulfur/selenium centered hydrogen bonds : A comprehensive computational study on models of oxo-, thio-, and seleno-nuleobase pairs unveils two- and threefold enhancements in the aromaticities of the thio- and seleno-nuleobases, respectively, compared to their oxygen counterpart. This is because of the unique characteristics of hydrogen bonds with sulfur and selenium, which need special attention in supramolecular chemistry.

17 July, 2020 - 00:00

Silyl protected nucleosides possess better biological activity. 2-O-silylated nucleosides were synthesized by trans opening of 1,2-anhydrosugar with nucleobases where HMDS acts both as activating, and silylating agent. Conformational analysis and biofilm inhibition activity of synthesized nucleosides were performed.

Synthesis and Glycosylation Properties of C6-Silylated <i>Ido</i>- and <i>Gluco</i>-Pyranosyl Donors

17 July, 2020 - 00:00

To study the influence of a silyl group on the reactivity and selectivity of glycosyl donors, two synthetic routes have been developed to obtain both D -glucosyl and L -idosyl donors with a silyl group attach to C6. The glycosylation and competition studies show that it enhances reactivity beyond what an O-benzyl group on C6 would do. In order to access C6-deoxy sugars, an efficient protodesilylation methodology is also described.

A High-Rate and Long-Life Rechargeable Battery Operated at −75 <sup>o</sup>C

7 July, 2020 - 00:00

As good as cold : A rechargeable battery based on Nb2O5 cathode and metallic lithium anode was fabricated, delivering a high rate (up to 5 C) and a long cycle life (100 cycles) at the ultra-low temperature of −75 °C, which can be attributed to the fast ion transport and low activation energy driven by the surface-controlled intercalation pseudocapacitive feature of Nb2O5 cathode.
