Impact of climate change on the distribution of Ligustrum leucanthum using MaxEnt modeling

Scientific Reports
Anthropogenic climate change has hastened habitat loss and fragmentation for wild animals and vegetation. However, the absence of sufficient and trustworthy information on their geographical distribution has impeded effective conservation management ...

Structural biology of ferritin nanocages

FEBS Letters, EarlyView.
Ferritin is a conserved iron‐storage protein that sequesters iron as a ferric mineral core within a nanocage, protecting cells from oxidative damage and maintaining iron homeostasis. This review discusses ferritin biology, structure, and function, and highlights recent cryo‐EM studies revealing mechanisms of ferritinophagy, cellular iron uptake, and ...

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.

Flax Planting Date Trial [PDF]

, 2015
Early seeding of flax generally produces the best yields and quality. Moderate temperatures and sufficient soil moisture during flowering and seed development are important for high yield and quality, and these conditions are more likely to occur with ...

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.

Genome-wide identification of BcMYB in Bupleurum Chinense DC. and its regulatory roles in saikosaponins synthesis under temperature stress

BMC Plant Biology
Background MYB transcription factors play critical roles in secondary metabolite biosynthesis in medicinal plants and are crucial for abiotic stress responses. However, no studies have identified BcMYB genes in Bupleurum chinense DC.

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
