Enzyme‐Catalysed Formation of Hydrocarbon Scaffolds from Geranylgeranyl Diphosphate Analogs with Shifted Double Bonds

open access: yesChemistry – A European Journal, EarlyView.
Four new geranylgeranyl diphosphate analogs with shifted double bonds were synthesized and together with the known analog iso‐GGPP I converted with 14 diterpene synthases. While two substrate analogs were not accepted by the enzymes, the other three analogs yielded compounds with skeletons that are not observed in nature.

Analysis of 3‐nitropropionic acid in Fabaceae plants by HPLC‐MS/MS

open access: yesPhytochemical Analysis, Volume 33, Issue 8, Page 1205-1213, December 2022., 2022
Abstract Introduction 3‐Nitropropionic acid (3‐NPA) is a toxic compound that can accumulate in esterified form in the Fabaceae family. In the Lotae tribe, many species have been identified as 3‐NPA producers (e.g., Securigera varia), while some of the genetically close Lotae plants were formerly reported as 3‐NPA‐free (e.g., Lotus corniculatus and ...

Enzymatic Treatment of Lignin in Alkaline Homogeneous Systems: A Review on Alkaliphilic Laccases

open access: yesChemSusChem, EarlyView.
This review summarizes the enzymatic treatment of lignin in alkaline homogeneous systems, with a focus on alkaliphilic laccases. Unlike native laccases that promote lignin polymerization under acidic conditions, these enzymes work in basic pH, where industrial lignins are soluble.
