Unexpected Dual Function of Plant YUCCA Enzymes Links Chlorophyll Catabolism to Auxin Homeostasis

Angewandte Chemie, EarlyView.
YUCCA enzymes are well known to catalyze the main step of auxin biosynthesis in plants. Here, a hitherto undescribed dual function was discovered, revealing that some YUCCAs also act in chlorophyll degradation. In vitro feedback regulation furthermore suggests a link between chlorophyll degradation and hormone homeostasis and a physiological role of ...

Automatically Defining Protein Words for Diverse Functional Predictions Based on Attention Analysis of a Protein Language Model

Advanced Science, EarlyView.
Understanding protein sequence–function relationships remains challenging due to poorly defined motifs and limited residue‐level annotations. An annotation‐agnostic framework is introduced that segments protein sequences into “protein words” using attention patterns from protein language models.

Additive and Partially Dominant Effects from Genomic Variation Contribute to Rice Heterosis

Advanced Science, EarlyView.
Additive and partially dominant effects, namely at mid‐parent levels or values between mid‐parent and parental levels, respectively, are the predominant inheritance patterns of heterosis‐associated molecules. These two genetic effects contribute to heterosis of agronomic traits in both rice and maize, as well as biomass heterosis in Arabidopsis ...

PCA‐Based Database Mining Enables the Discovery of Bacterial Carbene Transferases for Stereodivergent Cyclopropanation

Angewandte Chemie, EarlyView.
Database mining using principal component analysis (PCA)‐based clustering enabled discovery of bacterial enzymes capable of catalyzing stereodivergent cyclopropanation of styrene. Statistical analyses of sequence data further revealed characteristic structural properties of these enzymes, highlighting the potential of the bioinformatics tools for ...

Polydatin alleviates mitochondrial damage and apoptosis of lung epithelial cells by inhibiting toll‐like receptor 4‐dependent macrophage activation in asthma

Animal Models and Experimental Medicine, EarlyView.
The alleviation of asthma by polydatin is dependent on the blockage of the toll‐like receptor 4 (TLR4)/P2X7R synergy in macrophages. The blockage of the TLR4/P2X7R synergy results in decreased release and secretion of interleukin‐1β (IL‐1β) and IL‐18. In epithelial cells, low IL‐1β and IL‐18 levels inhibit mitochondrial damage and apoptosis.

Anatomical Associations Between Focal Mitochondrial Metabolism and Patterns of Neurodegeneration in Amyotrophic Lateral Sclerosis

Annals of Neurology, EarlyView.
Objective Amyotrophic lateral sclerosis (ALS) has a very specific neuroimaging signature, but the molecular underpinnings of the strikingly selective anatomic involvement have not elucidated to date. Accordingly, a large neuroimaging study was conducted with 258 participants to evaluate associations between patterns of neurodegeneration and focal ...
