Deciphering Tryptophan Oxygenation: Key Modulators of 2‐Oxindole Formation in MarE

open access: yesAngewandte Chemie International Edition, Accepted Article.
MarE, a heme‐dependent aromatic oxygenase with a histidyl axial ligated, catalyzes the monooxygention of β‐methyl‐L‐tryptophan, to form a 2‐oxindole scaffold central to maremycin biosynthesis. Although structurally similar to tryptophan 2,3‐dioxygenase (TDO), which initiates L‐tryptophan catabolism via dioxygenation, MarE exhibits distinct reactivity ...

Sulfur Mediated Interfacial Proton‐Directed Transfer Boosts Electrocatalytic Nitric Oxide Reduction to Ammonia over Dual‐site Catalysts

open access: yesAngewandte Chemie International Edition, Accepted Article.
Electrocatalytic nitric oxide reduction reaction (NORR) for ammonia (NH3) synthesis represents a sustainable strategy that simultaneously realizes the nitrogen cycle and resource integration. The key issue hindering the NORR efficiency is accelerating proton (*H) transfer to facilitate NO hydrogenation while inhibiting hydrogen evolution reaction (HER).

Comparison of Methods for the Preparation of Fatty Acid Methyl Esters for the Analysis of Omega‐3 Rich Oils by Gas Chromatography

open access: yesJournal of the American Oil Chemists' Society, EarlyView.
ABSTRACT Fatty acid analysis is required in a wide range of industries, and conversion to fatty acid methyl esters followed by gas chromatography is by far the most common method of analysis. However, despite widespread use, there is no consensus on which derivatization method should be used or how the methods compare.

Dendroglyphs, Pictographs and Social Identity in the Wet Tropics Rainforest of Northeastern Australia

open access: yesArchaeology in Oceania, EarlyView.
ABSTRACT This research examines rock art and dendroglyphs in the Wet Tropics of northeast Australia to investigate their relationship to linguistic social identity. The region was selected for its complex socio‐cultural landscape, marked by a diversity of languages in a distinct, relatively small area.
