Nonnative Thiol and Aniline Methylation, Including Enantioselective Dithiol Desymmetrization, by Multicomponent Cobamide‐Dependent Methyltransferases Using Unactivated Methyl Donors

Angewandte Chemie, EarlyView.
Mixed MtaABC/MtgABC methyltransferase systems were developed for non‐native thiol and aniline methylation using the unactivated methyl donors methanol and glycine betaine. The platform enabled site‐selective and enantioselective methylation with turnover number up to 6000, representing the first enantioselective non‐native catalysis by cobamide ...

Uptake and Glycosylation of Smoke-Derived Volatile Phenols by Cabernet Sauvignon Grapes and Their Subsequent Fate during Winemaking

Molecules, 2020
Wine made from grapes exposed to bushfire smoke can exhibit unpleasant smoky, ashy characters, which have been attributed to the presence of smoke-derived volatile phenols, in free or glycosylated forms.

Trends and mechanisms of Guaiacol Hydrodeoxygenation on Transition Metals - data

, 2022
This dataset was produced in course of a density functional theory (DFT) study of trends and mechanisms of guaiacol hydrodeoxygenation. Six transition metal surfaces, Fe (110), Co (0001), Ni (111), Cu (111), Pd (111) and Pt (111), were investigated as ...

Heterogenization of Heteropolyacid with Metal-Based Alumina Supports for the Guaiacol Gas-Phase Hydrodeoxygenation

Molecules, 2023
Because of the global necessity to decrease CO2 emissions, biomass-based fuels have become an interesting option to explore; although, bio-oils need to be upgraded, for example, by catalytic hydrodeoxygenation (HDO), to reduce oxygen content.

Thinking Inside the Box: A Novel Approach to Smoke Taint Mitigation Trials

Molecules, 2022
When bushfires occur near wine regions, grapevine exposure to smoke can taint grapes due to the uptake of smoke-derived volatile compounds that can subsequently impart unpleasant smoky, medicinal, burnt rubber and ashy characters to wine.

Evaluating the Susceptibility of Different Crops to Smoke Taint

Horticulturae
The potential for grapes and wine to be tainted following vineyard exposure to wildfire smoke is well established, with recent studies suggesting hops and apples (and thus beer and cider) can be similarly affected.
