Unlocking the Continuous Flow Asymmetric Hydrogenation of Olefins Through the Development of a Non‐Deactivating Immobilized Iridium Catalyst

Angewandte Chemie, EarlyView.
We have developed stable, robust, and reusable heterogeneous metal catalysts for an efficient continuous flow asymmetric hydrogenation (AH) of a variety of olefins, far beyond the typical benchmark AH. The products are produced continuously over long periods of time with high catalytic performance (up to 99% ee).

De novo formation of an aggregation pheromone precursor by an isoprenyl diphosphate synthase-related terpene synthase in the harlequin bug. [PDF]

, 2018
Insects use a diverse array of specialized terpene metabolites as pheromones in intraspecific interactions. In contrast to plants and microbes, which employ enzymes called terpene synthases (TPSs) to synthesize terpene metabolites, limited information ...

Seasonal measurements of total OH reactivity fluxes, total ozone loss rates and missing emissions from Norway spruce in 2011 [Discussion paper] [PDF]

, 2012
Numerous reactive volatile organic compounds (VOCs) are emitted into the atmosphere by vegetation. Most biogenic VOCs are highly reactive towards the atmosphere's most important oxidant, the hydroxyl (OH) radical.

Metabolic Engineering for the Biosynthesis of Pentalenene in the Rapidly Growing Bacterium Vibrio natriegens

Fermentation
Vibrio natriegens (V. natriegens) is an emerging synthetic biology chassis characterized by rapid growth, and its potential for the synthesis of sesquiterpenes (such as pentalenene) has not been developed.

Linking Terpene Synthases to Sesquiterpene Metabolism in Grapevine Flowers

Frontiers in Plant Science, 2019
Grapevine (Vitis vinifera L.) terpene synthases (VviTPS) are responsible for the biosynthesis of terpenic volatiles. Volatile profiling of nine commercial wine cultivars showed unique cultivar-specific variation in volatile terpenes emitted from ...

Seeing the Forest through the (Phylogenetic) Trees: Functional Characterisation of Grapevine Terpene Synthase (VviTPS) Paralogues and Orthologues

Plants, 2021
Gene families involved in specialised metabolism play a key role in a myriad of ecophysiological and biochemical functions. The Vitis vinifera sesquiterpene synthases represent the largest subfamily of grapevine terpene synthase (VviTPS) genes and are ...
