Multienzyme cascade for synthesis of hydroxytyrosol via engineered Escherichia coli

open access: yesScientific Reports
Hydroxytyrosol, a fine chemical, is widely utilized in food and pharmaceutical industries. In this study, we constructed a pathway to produce hydroxytyrosol by co-expressing tyrosin-phenol lyase (TPL), L-amino acid dehydrogenase (aadL), α-keto acid ...

Peroxide‐Assisted Solvate Engineering Enables Record‐High Birefringence in a Solar‐Blind Transparent Crystal

open access: yesAngewandte Chemie International Edition, EarlyView.
H2O2‐directed solvate engineering reorganizes ∞[4HP] (4‐hydroxypyridine) chains from a crossed arrangement into a nearly parallel packing through strengthened hydrogen‐bonding interactions. The resulting peroxide‐containing crystal, 4HP·H2O2, exhibits a solar‐blind UV cutoff edge (278 nm) and giant birefringence (0.609 @ 546 nm). This work demonstrates

Complete mitochondrial genome of Kentrochrysalis streckeri (Lepidoptera: Sphingidae) and phylogenetic analysis

open access: yesMitochondrial DNA. Part B. Resources, 2022
In this study, we sequenced the complete mitogenome of Kentrochrysalis streckeri (Staudinger, 1880). The complete mitogenome sequence of K. streckeri is circular, 15,253 bp in size and contains 13 protein-coding genes (PCGs), two ribosomal RNA (rRNA ...

Research progress and current status of dynamic wave propagation characteristics in rock mass: A review

open access: yesDeep Underground Science and Engineering, EarlyView.
This review elucidates the velocity–dispersion–attenuation coupling mechanisms of wave propagation in rock masses, compares six representative models, and reveals how pressure, temperature, mineral composition, and anisotropy jointly control dynamic responses in complex geological media.

Museomics Deciphers the Phylogeographic Differentiation and Conservation Status of a Montane Pheasant

open access: yesIntegrative Zoology, EarlyView.
Museum specimens provide a rich source of historical DNA, enabling insights into phylogenetic relationships and demographic history of the endangered Koklass Pheasant. Our findings uncovered a previously unrecognized population in Guizhou province and highlighted elevated extinction risk in populations from Anhui province and Southern China, informing ...

(Ultra)high‐Pressure Metamorphism in Sedimentary Versus Basaltic Rocks: Insights From a Variscan Mélange in the South Carpathians

open access: yesJournal of Metamorphic Geology, EarlyView.
ABSTRACT Reconstructing the pressure–temperature–time (P–T–t) evolution of (ultra)high‐pressure rocks is essential for constraining subduction and collisional dynamics. Subduction zones are often investigated using basic eclogites, whereas nonbasic high‐pressure rocks remain comparatively understudied, potentially hindering a comprehensive ...

Phenylpropanoid volatile synthesis during sequential roasting of Lu’an Guapian green tea: Differential activities of gallocatechin isomers in aromatic amino acid pyrolysis and Maillard reactions

open access: yesFood Chemistry: X
Sequential roasting is a unique technology for processing of Lu’an Guapian green tea. The chemical base and the mechanisms underpinning roasting-induced flavor and aroma changes are not fully understood. Here, variations in volatiles, catechins, and free
