Dual Disruption of the Immune Cytokine Spätzle Facilitates Fungal Infection of Diverse Insect Hosts

Advanced Science, EarlyView.
The Toll pathway is essential for insect defense against fungal pathogens. This works reports that fungal parasites employ two divergent virulent effectors to target the Toll receptor ligand Spätzle: a metalloprotease degrading it and a hairpin‐like effector hijacking it to block signal transduction. This dual strategy enables the fungus to kill a wide

Cupin‐Type Dimethylsulfoniopropionate Lyase from Pelagibacter ubique (DddKPu) Catalyzes Aza‐Michael Addition of Primary and Secondary Amines to Acrylic Acid

Angewandte Chemie, EarlyView.
A dimethylsulfoniopropionate lyase (DddK) was identified as an efficient aza‐Michaelase for the addition of amines to acrylate. Screening 74 amines with wild‐type DddK and its W26G variant yielded N‐substituted and N,N‐disubstituted β‐amino acids in 30%–93% isolated yield.

Acidogenesis‐Propelled Coordination Transition in Light‐Triggered Fe‐Polyphenol Polymer for Reactive Oxygen Species‐Augmented Antitumor Therapy

Advanced Science, EarlyView.
A novel iron‐polyphenol‐photoacid coordination polymer (FeBPs) is designed to achieve red light‐triggered external acidification and internal coordination regulation, where this light‐controlled acidification induces coordination changes that enhance Fe active site exposure and provide H+ for beneficial Fe3+/Fe2+ conversion, thereby accelerating ROS ...

Formation of Chloroplast pigments and photosynthetic potential of chloroembryos in angiosperms [PDF]

, 1989
Chlorophyll bearing property of embryos in Angiosperms or its absence is of particular interest because it is not only an embryological but also physiological phenomenon since it may be intimately related to certain peculiarities of plant metabolism

The study of antimicrobial activity of 2-((4-R-3-(morpholinomethylene)-4H-1,2,4-triazole-5-yl)thio)acetic acid salts

Zaporožskij Medicinskij Žurnal, 2016
The purpose of the work was to study the antimicrobial activity of 2-((4-R-3-(morfolinomethylene)-4H-1,2,4-triazole-5-yl)thio) acetic acid salts by "hanging drop" and “serial dilution” methods in broth (limiting concentration option) and establish some ...

Insect I‐Type Lysozymes Function as Antiviral Proteases by Forming Biomolecular Condensates

Advanced Science, EarlyView.
Upon rice viral infection, the insect vector activates the Toll–MyD88–Dorsal signaling cascade, inducing i‐type lysozyme (Lyz‐I1) expression. Lyz‐I1 functions as an antiviral protease through its conserved catalytic dyad Glu/Asp (E/D), mediating cleavage of viral proteins at specific Lys (K) residues.
