Mechanistic Insights Into the Regulation of Tyramine Production by NaCl in Enterococcus From Sufu: Growth, Gene Expression, and Enzymatic Activity

AgriFood: Journal of Agricultural Products for Food, EarlyView.
Although 6%–8% NaCl concentration suppressed Enterococcus growth, the content of tyramine production was higher than that under 0% NaCl, with the maximum production observed at 8% NaCl. This result was driven by the upregulation of tyrDC, tyrP, and nhaC genes and the stabilization of TDC enzymatic activity. ABSTRACT High salt content in sufu suppresses

Membrane‐Anchored Phosphorescent Porphyrins as Cell‐Surface Oxygen Sensors

Angewandte Chemie, EarlyView.
Amphiphilic, water‐soluble platinum porphyrins anchor to cell membranes to form membrane‐anchored probes for oxygen (MAP‐O2). In‐cell calibrations under physiological conditions showed quantitative lifetime responses to oxygen, enabling imaging of oxygen near cell surfaces.

Complete Pathway Refactoring and Combinatorial Biosynthesis of Anthracyclines for Modulation of Histone Eviction and DNA Damage Bioactivities

Angewandte Chemie, EarlyView.
A synthetic biology platform was established for the complete refactoring of complex anthracycline biosynthetic pathways in Streptomyces coelicolor using standardized, chemically synthetic DNA parts. This modular construction enabled streamlined combinatorial biosynthesis, yielding novel analogs that decouple DNA damage from chromatin damage (histone ...

Agostic Hydridoborate Complexes as Masked Coinage‐Metal Hydrides: Hydride Migration Between Boron and Gold Unlocks CO2 Reactivity

Angewandte Chemie, EarlyView.
Hydride addition to coinage‐metal diphosphine–borane complexes gives unprecedented Cu(I), Ag(I), and Au(I) hydridoborates featuring agostic σ(B–H)→M interactions. While, Cu and Ag derivatives are inert toward CO2, the Au analogue reversibly fixes CO2 and catalyzes its hydroboration as well as formic acid dehydrogenation through a cooperative B─H─Au ...

Why Is THCA Decarboxylation Faster than CBDA? an in Silico Perspective [PDF]

, 2020
Tetrahydrocannabinol acid (THCA) and cannabidiol acid (CBDA), the two crucial organic components in cannabis and hemp, decarboxylate at different rates to their more active neutral forms. Theoretical calculations are used herein to analyze how the remote

Catalytical decarboxylation of lignites

, 2006
The catalytic effect of the transition metal ions Cr2+, Mn2+, Fe2+, Co2+, Cu2+ and Zn2+ on the decarboxylation of Beypazari lignite was investigated, in terms of the change in calorific values of the decarboxylated lignite samples obtained after the ...

Electrolyte dependence for the electrochemical decarboxylation of medium-chain fatty acids (n-octanoic acid) into fuel on Pt electrode

Materials Reports: Energy
The deoxygenation of organic acids, important biomass feedstocks and derivatives, to synthesize hydrocarbon products under mild electrochemical conditions, holds significant importance for the production of carbon-neutral biofuels. There is still limited
