Secretory ferritins mediate iron delivery during magnetite tooth formation in chitons

The paper identifies secretory ferritins as iron transporters in chitons, showing they deliver iron to developing teeth via hemolymph.

The 329HHK331 motif is essential for Alzheimer's disease tau filament fold

The paper investigates the role of the 329HHK331 motif in Alzheimer's disease tau filament formation and shows that mutations in this region affect filament structure and seeding activity.

Engineering of ATP synthase for enhancement of proton-to-ATP ratio

This study engineered ATP synthase to increase the H+/ATP ratio beyond natural limits, enabling ATP synthesis at lower proton motive force.

Parasitoid wasp venoms degrade Drosophila imaginal discs for successful parasitism

This study identifies two venom proteins from Asobara japonica that induce imaginal disc degradation in Drosophila, essential for parasitism success.

Structural characterization of pyruvic oxime dioxygenase, a key enzyme of heterotrophic nitrification

This study determines the crystal structure of pyruvic oxime dioxygenase (POD) from Alcaligenes faecalis, revealing its catalytic mechanism and structural features involved in heterotrophic nitrification.

Size matters: optimal mask diameter and box size for single-particle cryogenic electron microscopy

This paper optimizes mask diameter and box size for 200 keV cryo-EM to improve resolution for proteins under 200 kDa.

Sub-3 Å resolution structure of 110 kDa nitrite reductase determined by 200 kV cryogenic electron microscopy

The paper determines the sub-3 Å resolution cryo-EM structures of Achromobacter cycloclastes NiR at two pH values, identifies structural artifacts, and suggests local changes around the Cu site.
