Revealing the Active State of a Cu/ZnO:Al Catalyst During Reverse Water–Gas Shift Reaction in an Operando Microwave Absorption Study

Angewandte Chemie International Edition, EarlyView.
We investigated the transformations of an industrially relevant CuO/ZnO/Al2O3 pre‐catalyst during its activation and under operation in reverse water–gas shift reaction. Changes of the dielectric properties induced by H2, which acts as an electron donor and oxygen provided by CO2 acting as an electron sink are correlated with the catalytic yield, which

Mechanistic Characterisation of a Diterpene Synthase for Chryseojoostenes A–E from Chryseobacterium Joostei

Angewandte Chemie International Edition, EarlyView.
The bacterial diterpene synthase CjCS for chryseojoostenes was mechanistically characterised through labelling experiments, density functional theory (DFT) calculations, and conversion of substrate analogs with blocked reactivity. Site‐directed mutagenesis gave access to minor enzyme products, including chryseojoostene E, whose biosynthesis involves a ...
