Evolutionary Relationships Between the Laccase Genes of Polyporales: Orthology-Based Classification of Laccase Isozymes and Functional Insight From Trametes hirsuta

Frontiers in Microbiology, 2019
Laccase is one of the oldest known and intensively studied fungal enzymes capable of oxidizing recalcitrant lignin-resembling phenolic compounds. It is currently well established that fungal genomes almost always contain several non-allelic copies of ...

Bifunktionale Cosubstrate ermöglichen Threonin‐Dehydrogenase katalysierte chemoenzymatische Pyrrolsynthese

Angewandte Chemie, EarlyView.
Klassische Knorr‐Chemie trifft auf moderne Biokatalyse. Die Threonindehydrogenase erzeugt aus l‐Threonin Aminoaceton, welches direkt in einer chemoenzymatischen Knorr‐Pyrrolsynthese abgefangen wird. Ein bifunktionales β‐Dicarbonylsubstrat dient sowohl als Pyrrolbaustein als auch als Hydridakzeptor für integrierte NAD+‐Recyclierung und ermöglicht die ...

Asymmetric synthesis of a high added value chiral amine using immobilized ω-transaminases

Beilstein Journal of Organic Chemistry, 2019
Chiral N-heterocyclic molecules and in particular compounds with an amino functional group such as 3-aminopiperidine are valuable intermediates for the production of a large number of bioactive compounds with pharmacological properties.

Nucleotide sugar biosynthesis occurs in the glycosomes of procyclic and bloodstream form Trypanosoma brucei.

PLoS Neglected Tropical Diseases, 2021
In Trypanosoma brucei, there are fourteen enzymatic biotransformations that collectively convert glucose into five essential nucleotide sugars: UDP-Glc, UDP-Gal, UDP-GlcNAc, GDP-Man and GDP-Fuc. These biotransformations are catalyzed by thirteen discrete

Dual‐Function Cosubstrates Enable Threonine Dehydrogenase‐Driven Chemoenzymatic Pyrrole Synthesis

Angewandte Chemie International Edition, EarlyView.
Classical Knorr chemistry meets contemporary biocatalysis. Threonine dehydrogenase generates aminoacetone from l‐threonine, which is directly intercepted in a chemoenzymatic Knorr pyrrole synthesis. A dual‐function β‐dicarbonyl substrate serves as both pyrrole precursor and hydride acceptor for integrated NAD+ recycling, affording substituted pyrroles ...

Lactones with Methylcyclohexane Systems Obtained by Chemical and Microbiological Methods and Their Antimicrobial Activity

Molecules, 2015
Eight new lactones (δ-chloro-, δ-bromo- and δ-iodo-γ-lactones), each with a methylcyclohexane ring, were obtained by chemical means from (4-methylcyclohex-2-en-1-yl) acetic acid or (6-methylcyclohex-2-en-1-yl) acetic acid.

Effects of Cellulase and Lactobacillus plantarum Supplementation on Fermentation Characteristics, In Situ Degradability, and Microbial Community Dynamics of Apple Pomace Silage

Animal Research and One Health, EarlyView.
This study aimed to investigate the effects of cellulase and Lactobacillus plantarum on the silage quality, in situ digestibility, and microbial communities of apple pomace silage. The combined supplementation of cellulase and Lactobacillus plantarum in apple pomace silage improved fermentation quality and enhanced rumen utilization efficiency.
