Update: Enzymatische Synthese für industrielle Anwendungen

Angewandte Chemie, Volume 137, Issue 27, July 1, 2025.
Die Biokatalyse hat sich zu einer nachhaltigen und wettbewerbsfähigen Alternative zur herkömmlichen chemischen Synthese entwickelt und ermöglicht die enzymbasierte Herstellung nicht nur von chemischen Grundstoffen, sondern auch von (nicht natürlichen) Aminosäuren, (seltenen) Zuckern und synthetischen Nukleotiden.

An Update: Enzymatic Synthesis for Industrial Applications

Angewandte Chemie International Edition, Volume 64, Issue 27, July 1, 2025.
Biocatalysis has become a sustainable and cost‐competitive alternative to established chemical synthesis, enabling the enzyme‐based production of not only commodity chemicals but (non‐natural) amino acids, (rare) sugars, as well as synthetic nucleotides.

Sulfonamides identified as plant immune-priming compounds in high-throughput chemical screening increase disease resistance in Arabidopsis thaliana [PDF]

, 2012
Plant activators are agrochemicals that protect crops from diseases by activating the plant immune system. To isolate lead compounds for use as practical plant activators, we screened two different chemical libraries composed of various bioactive ...

Membrane-bound glycerol dehydrogenase catalyzes oxidation of D-pentonates to 4-keto-D-pentonates, D-fructose to 5-keto-D-fructose, and D-psicose to 5-keto-D-psicose [PDF]

Bioscience, Biotechnology, and Biochemistry, 2017
Abstract A novel oxidation of D-pentonates to 4-keto-D-pentonates was analyzed with Gluconobacter thailandicus NBRC 3258. D-Pentonate 4-dehydrogenase activity in the membrane fraction was readily inactivated by EDTA and it was reactivated by the addition of PQQ and Ca2+. D-Pentonate 4-dehydrogenase was purified to two different subunits,

Reconstitution of Methionine Cycle With ATP Regeneration for Whole‐Cell Catalysis of Creatine Production in Engineered Escherichia coli

Microbial Biotechnology, Volume 18, Issue 5, May 2025.
In this study, we constructed a CR biosynthesis pathway in E. coli by introducing exogenous AGAT and GAMT. We integrated the reconstitution methionine cycle with a polyphosphate kinase‐based ATP regeneration system, achieving a CR titre of 5.27 g/L with a productivity of 0.22 g/L/h.

Conversion of xylan by recyclable spores of Bacillus subtilis displaying thermophilic enzymes [PDF]

, 2017
Background: The Bacillus subtilis spore has long been used to display antigens and enzymes. Spore display can be accomplished by a recombinant and a non-recombinant approach, with the latter proved more efficient than the recombinant one.

Crystal structure of 6-deoxy-α-l-psicofuranose

Acta Crystallographica Section E: Crystallographic Communications, 2015
The title compound, C6H12O5, was crystallized from an aqueous solution of 6-deoxy-l-psicose (6-deoxy-l-allulose, (3S,4S,5S)-1,3,4,5-tetrahydroxyhexan-2-one), and the molecule was confirmed as α-furanose with a 3T4 (or E4) conformation, which is a ...
