Ion Activation Methods for Top‐Down Proteomics

Mass Spectrometry Reviews, EarlyView.
ABSTRACT Mass spectrometry (MS) has emerged as a premier method used to characterize the sequences of proteins. Top‐down proteomics aims to capture the multiple sources of structural diversity reflected in proteins, such as those that arise from alternative RNA splicing events or the addition of post‐translational modifications. Tandem MS (i.e., MS/MS)

Topology‐Encoded Charge Polarity Governs Multiphase Organization in Intrinsically Disordered Protein Polymer Condensates

Small, EarlyView.
Electrostatic topology is shown to program phase separation and internal organization in thermoresponsive intrinsically disordered protein polymer (IDPP) condensates. By comparing oppositely charged IDPPs with a covalent diblock, chain connectivity is revealed to control charge compensation, dense‐phase micropolarity, miscibility, and apparent acid ...

Engineering Nitrogen Vacancies in Polymeric Carbon Nitride to Promote Interfacial Electron Transfer for Visible‐Light Driven Hydrogen Evolution

Small, EarlyView.
By integrating nitrogen‐vacancy engineering with interfacial electronic optimization, this study achieves a marked enhancement in the hydrogen evolution performance of g‐C3N4‐based photocatalysts, providing a new design paradigm for photocatalytic water splitting.

Bridging the divide between models of animal‐driven and microbial‐driven biogeochemical cycling: A zoogeochemistry‐informed framework

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Most current terrestrial biogeochemical models formalize biogeochemical cycling as predominantly controlled by processes involving plants and soil microbes. However, growing evidence indicates that above‐ground animals could exert controlling feedback effects that alter

The superposition method for the reconstruction of food webs

Methods in Ecology and Evolution, EarlyView.
Abstract Understanding trophic positions is essential for analysing complex food webs. While calculating these positions can be straightforward when feeding relationships and their proportions are known, determining diet coefficients traditionally requires substantial time and effort.

NITROGEN BALANCE IN SOIL PROFILE AS AFFECTED BY DIFFERENT SOIL TYPE, SOIL WATER REGIMES, NITROGEN RATE AND APPLICATION METHODS USING 15N TRACER TECHNIQUE

, 2014
The interaction effect of ?Soil type, Soil water regime, Nitrogen fertilizer application Rates and Timing? on Nitrogen balancein soil were studied; in terms of nitrogen gained by plant portions, remained in soil, and losses through different ways under wheat (Triticum aestivum L.

Stable Isotope Analysis as a Tool to Prevent Illicit Wildlife Trade of Songbirds in Brazil

Animal Conservation, EarlyView.
Feather isotopes provide clear differences between wild and captive songbirds in Brazil. Combining multiple isotopes improved classification accuracy and revealed individuals falsely declared as captive‐bred. These results demonstrate the potential of isotope analysis to detect wildlife laundering in the bird trade.

The R203W substitution drives PACS‐1 syndrome by disrupting intramolecular regulation

The FEBS Journal, EarlyView.
The middle region (MR) of PACS‐1 controls engagement with specific partner proteins. This manuscript presents the structure of the Furin binding region (FBR) and how interactions with partners are regulated through the interplay between a basic patch in the FBR and an acidic cluster in the MR.

Directional information flow in human frataxin defines allosteric pathways connecting the hydrophobic core to the iron‐binding ridge

The FEBS Journal, EarlyView.
Human frataxin deficiency causes Friedreich's ataxia, yet how iron‐binding events are communicated across the protein is unclear. Using transfer entropy analysis of molecular dynamics simulations, we identify buried hydrophobic core leucines (LEU136, LEU140) as the source of directional signaling toward the iron‐binding acidic ridge.
