ABSTRACT BorF is a short‐chain flavin reductase from a desert soil bacterium that uses NADH to reduce FAD to FADH2, which is used by the tryptophan‐6‐halogenase BorH to chlorinate tryptophan in the biosynthetic pathway of borregomycin A. The X‐ray crystal structure of BorF bound to FAD was solved to 2.37 Å by molecular replacement.

NMR Line Shape Analysis of a Multi-state Ligand Binding Mechanism in Chitosanase [PDF]
Chitosan interaction with chitosanase was examined through analysis of spectral line shapes in the NMR HSQC titration experiments. We established that the substrate, chitosan hexamer, binds to the enzyme through the three-state induced-fit mechanism with

The continuing significance of chiral agrochemicals
In the time frame 2018–2023, around 43% of the 35 chiral agrochemicals introduced to the market (herbicides, fungicides, insecticides, acaricides, and nematicides) contain one or more stereogenic centers in the molecule, and almost 69% of them have been marketed as racemic mixtures of enantiomers or stereoisomers.

Network analysis of functional genes among prokaryotes, and eukaryotes in natural and artificial rivers. Abstract Periphyton in aquatic ecosystems plays vital roles in the elemental cycle process and is vulnerable to anthropogenic interference. However, few studies have explored the elemental cycles of carbon (C), nitrogen (N), phosphorus (P), and ...

The scalable synthesis of target molecules is crucial for applications such as biological evaluation in medicinal chemistry and even industrial production. We described recent advances in chiral Brønsted acid–catalyzed asymmetric allylboration, which enables access to previously elusive chiral building blocks, and highlight its application to the ...

Phosphorus gradient yields threshold MAOC response governed by microbial and stoichiometric controls
Read the free Plain Language Summary for this article on the Journal blog. Abstract Phosphorus (P) availability is a key factor that mediates the formation of mineral‐associated organic carbon (MAOC) in soils, yet reported responses to P fertilization are often inconsistent.

Severe symptoms of root rot on sugar beet have been observed in Poland and Germany since 2001. The symptom classification suggested girth scab as it was mistakenly classified on the basis of current classification, e.g. in LIZ.

Characterization of the dynamic microbiome evolution across thrips species
Comprehensive survey of the microbiome in thrips. The dominant bacterial genera found in thrips include intracellular ones, such as Wolbachia and Spiroplasma, and extracellular ones, including Serratia, Pantoea, and Acinetobacter. We isolated and sequenced high‐quality genomes of two dominant symbionts, Pantoea dispersa and Serratia marcescens.
