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

Angewandte 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 ...

Greek Protected Designation of Origin Xinomavro Wines: A Deep Dive into Their Chemical Composition and Geographical Origin by Using Ultra High Performance Liquid Chromatography–Trapped Ion Mobility Spectrometry–Quadrupole Time of Flight–Mass Spectrometry

Analysis &Sensing, EarlyView.
Greek protected designation of origin Xinomavro wines are analyzed with ultra high performance liquid chromatography–trapped ion mobility spectrometry–quadrupole time of flight‐mass spectrometry (UHPLC‐TIMS‐QTOF‐MS). Both target and not‐target screening approaches are employed, leading to the identification and quantification of several polyphenols and
