Dispersion‐Enhanced Nitrogen‐Centered Photocatalysis of the Direct Hydrogen Atom Transfer

open access: yesAngewandte Chemie, EarlyView.
Nitrogen‐centered acridine photocatalysts for direct hydrogen atom transfer have been developed, leveraging dispersion interactions to enhance photocatalytic activity. This approach enables diverse functionalization reactions of strong C─H bonds even under cryogenic conditions and provides a new strategy for boosting the efficiency of direct HAT ...

In vitro oxidative decarboxylation of free fatty acids to terminal alkenes by two new P450 peroxygenases

open access: yesBiotechnology for Biofuels, 2017
BackgroundP450 fatty acid decarboxylases represented by the unusual CYP152 peroxygenase family member OleTJE have been receiving great attention recently since these P450 enzymes are able to catalyze the simple and direct production of 1-alkenes for ...

Systematic Metabolic Engineering and Model‐Guided Optimization for High‐Level Production of L‐Theanine From Xylose in Escherichia Coli

open access: yesAdvanced Science, EarlyView.
This study is pioneering in constructing the shortest known synthetic pathway for L‐theanine production from xylose within E coli. Through comprehensive metabolic engineering strategies, our engineered strain achieved the highest reported L‐theanine titer from xylose, with a titer of 95.42 g/L, and a yield of 0.55 g/g.

Unexpected Dual Function of Plant YUCCA Enzymes Links Chlorophyll Catabolism to Auxin Homeostasis

open access: yesAngewandte Chemie, EarlyView.
YUCCA enzymes are well known to catalyze the main step of auxin biosynthesis in plants. Here, a hitherto undescribed dual function was discovered, revealing that some YUCCAs also act in chlorophyll degradation. In vitro feedback regulation furthermore suggests a link between chlorophyll degradation and hormone homeostasis and a physiological role of ...

Halogen‐Bond Coupled Halogenated‐π‐Conjugation Enables Giant Birefringence in Hydrogen‐Bonded Organic Frameworks

open access: yesAdvanced Science, EarlyView.
The perfect crystal packing achieved via the halogen‐bond (XB) coupled halogenated‐π‐conjugation strategy effectively induces an ultrahigh birefringence (Δn = 0.97), which exhibits promising potential in polarization control and phase modulation.

Electrochemical Degradation of Perfluoroalkyl Sulfonates via Sulfonate to Carboxylate Conversion

open access: yesAngewandte Chemie, EarlyView.
We demonstrate a novel approach for the degradation of perfluoroalkyl sulfonic acids (PFSAs) involving a controlled, electromediated, sulfonate‐to‐carboxylate headgroup conversion. We apply this method to shorter chain PFSAs and provide key mechanistic insights that contribute to a broader understanding of the molecular pathways underlying pollutant ...
