Deciphering the properties and reaction mechanism of anhydromevalonate phosphate decarboxylase, a prenylated flavin mononucleotide‐dependent enzyme in the archaeal mevalonate pathway

open access: yesThe FEBS Journal, EarlyView.
Characterization of anhydromevalonate phosphate decarboxylase, the UbiD‐family decarboxylase involved in the archaeal mevalonate pathway, was conducted. The enzyme is responsible for the biosynthesis of isoprenoids, such as archaeal membrane lipids, respiratory quinones, and dolichols.

Comparative evaluation of noncanonical amino acids as site‐specific NMR probes for the complex of E. coli SSB with single‐stranded DNA without isotope labelling

open access: yesThe FEBS Journal, EarlyView.
Genetic encoding of noncanonical amino acids (ncAA) enables their site‐specific installation in proteins. This work compares the nuclear magnetic resonance (NMR) performance of different ncAAs in a large protein−DNA complex (~ 100 kDa) without isotope labelling. The ncAAs deliver readily detectable NMR signals in the complex between E.

Opposing roles of DGAT‐mediated lipid droplet biogenesis in the regulation of ferroptosis sensitivity

open access: yesThe FEBS Journal, EarlyView.
Ferroptosis is driven by unrestricted peroxidation of polyunsaturated fatty acyl (PUFA) chains in membrane phospholipids. In triple‐negative breast cancer cells, lipid droplets (LDs) sequester dietary PUFAs, limiting their incorporation into membrane phospholipids, preventing mitochondrial damage, and reducing lipid peroxidation and ferroptosis.

A new branch of mammalian vitamin B6 metabolism: AKR1C‐mediated conversion of pyridoxal to pyridoxine and 4‐pyridoxolactone

open access: yesThe FEBS Journal, EarlyView.
Pyridoxal 5′‐phosphate (PLP) homeostasis relies on salvage enzymes, yet key metabolic branches remain undefined. We identify AKR1C isozymes as previously undescribed contributors that convert pyridoxal into pyridoxine or 4‐pyridoxolactone through reductase and dehydrogenase activities.

Tyrosine residues at the substrate binding site in human NQO1 homodimer: Protein conformational dynamics and optimization of substrate binding geometry

open access: yesThe FEBS Journal, EarlyView.
Human NAD(P)H:quinone oxidoreductase 1 is a homodimeric flavoenzyme crucial for redox metabolism and linked to significant health issues. Point mutations at Tyr126 and Tyr128 demonstrate their essential roles in optimizing substrate binding geometry for catalysis, as well as in half‐site reactivity and conformational dynamics during the enzyme's ...

Lethal Effects of the Wild Potato Solanum bulbocastanum on the Planthopper Pentastiridius leporinus, a Vector of Bacterial Pathogens in Potato

open access: yesJournal of Applied Entomology, EarlyView.
ABSTRACT The planthopper Pentastiridius leporinus [Hemiptera: Cixiidae] is a vector of the two plant pathogenic bacteria ‘Candidatus Arsenophonus phytopathogenicus’ and ‘Candidatus Phytoplasma solani’ causing ‘bacterial potato tuber wilt’ in potato.

Multi‐omics analyses shed lights on the evolution and fruit development of Chinese raspberries (Rubus spp.)

open access: yesJournal of Integrative Plant Biology, EarlyView.
High‐quality genomes of four wild raspberry species, analysis of their genetic relationships, identification of centromeres as markers for tracing their hybrid origins, exploration of fruit quality regulation, and discovery of a gene blocking anthocyanin transport and thus causing yellow fruits provides valuable resources for raspberry breeding ...

Key metabolites secreted by Chlorella vulgaris alleviate salt stress in soybean seedlings

open access: yesJournal of Integrative Plant Biology, EarlyView.
Chlorella vulgaris secretes exosome‐derived linolenic acid and inosine, which alleviate salt stress and enhance salt tolerance in soybean seedlings by activating stress‐responsive signaling networks. ABSTRACT Soil salinization is a major abiotic stress factor that reduces soybean production.
