Structural insights into an engineered feruloyl esterase with improved MHET degrading properties

FEBS Letters, EarlyView.
A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system

FEBS Letters, EarlyView.
Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

NextDenovo: an efficient error correction and accurate assembly tool for noisy long reads

Genome Biology
Long-read sequencing data, particularly those derived from the Oxford Nanopore sequencing platform, tend to exhibit high error rates. Here, we present NextDenovo, an efficient error correction and assembly tool for noisy long reads, which achieves a high

Seasonal differences and downstream transport of terrestrial vertebrate eDNA: Insights from integrated camera-trap survey and water eDNA metabarcoding

Global Ecology and Conservation
Effective biodiversity conservation requires efficient, comprehensive, and cost-effective monitoring tools. While environmental DNA (eDNA) metabarcoding is widely used for aquatic biodiversity assessments, its application for monitoring terrestrial ...

A methionine‐lined active site governs carbocation stabilization and product specificity in a bacterial terpene synthase

FEBS Letters, EarlyView.
This study reveals a unique active site enriched in methionine residues and demonstrates that these residues play a critical role by stabilizing carbocation intermediates through novel sulfur–cation interactions. Structure‐guided mutagenesis further revealed variants with significantly altered product profiles, enhancing pseudopterosin formation. These

Anti-HIV-1 Activity of the Integrase Strand Transfer Inhibitor ACC017

Viruses
HIV-1 integrase strand transfer inhibitors (INSTIs) are pivotal to antiretroviral therapy. However, the emergence of drug-resistant mutations necessitates the development of new agents. Here, we present ACC017 as a novel INSTI candidate.

Valosin‐containing protein counteracts ATP‐driven dissolution of FUS condensates through its ATPase activity in vitro

FEBS Letters, EarlyView.
Biomolecular condensates formed by fused in sarcoma (FUS) are dissolved by high ATP concentrations yet persist in cells. Using a reconstituted system, we demonstrate that valosin‐containing protein (VCP), an AAA+ ATPase, counteracts ATP‐driven dissolution of FUS condensates through its D2 ATPase activity.

A 150‐Year Avian Extinction Debt Forewarns a Global Species Crisis and Highlights Conservation Opportunities

Conservation Letters
Humans have caused pervasive wildlife habitat loss by transforming most of the Earth's terrestrial surface, while unexpectedly limited species have consequently gone extinct.

Diversity and complexity in neural organoids

FEBS Letters, EarlyView.
Neural organoid research aims to expand genetic diversity on one side and increase tissue complexity on the other. Chimeroids integrate multiple donor genomes within single organoids. Self‐organising multi‐identity organoids, exogenous cell seeding, or enforced assembly of region‐specific organoids contribute to tissue complexity.

Forward and reverse genomic screens enhance the understanding of phenotypic variation in a large Chinese rhesus macaque cohort

Nature Communications
Combining genotype and phenotype data promises to greatly increase the value of macaque as biomedical models for human disease. Here we launch the Macaque Biobank project by deeply sequencing 919 captive Chinese rhesus macaques (CRM) while assessing 52 ...
