Investigating the role of a conserved hydrophobic pocket of gp41 in the anti‐HIV activity of fusion inhibitors

open access: yesProtein Science, Volume 35, Issue 6, June 2026.
Abstract Membrane fusion between HIV and host cells requires interaction between the N‐terminal and C‐terminal repeat regions (NHR and CHR) of the gp41 envelope subunit. A deep hydrophobic pocket (HP) on the surface of NHR is considered crucial in this interaction.

Time-resolved serial synchrotron and serial femtosecond crystallography of heme proteins using photocaged nitric oxide

open access: yesIUCrJ
Time-resolved X-ray crystallography is undergoing a renaissance due to the development of serial crystallography at synchrotron and XFEL beamlines. Crucial to such experiments are efficient and effective methods for uniformly initiating time-dependent ...

Intrinsically dominant conformational diversity in PDZ1 within the tandem PDZ1–PDZ2 of human syntenin‐1 underlined by crystal structures

open access: yesProtein Science, Volume 35, Issue 6, June 2026.
Abstract The intrinsic dynamic asymmetry between homologous PDZ domains in multidomain scaffold proteins offers insight into how they achieve multivalent partner recognition. Through a systematic x‐ray crystallographic analysis of tandem PDZ1–PDZ2 domains in human syntenin‐1 (SDCBP/MDA‐9), we solved nine high‐resolution structures and uncovered ...

Stabilizing Plasmodium falciparum proteins for small molecule drug discovery

open access: yesProtein Science, Volume 35, Issue 6, June 2026.
Abstract Early‐stage drug discovery relies on the availability of stable protein for reliable biophysical characterization of ligand binding. However, many Plasmodium falciparum proteins are challenging to produce in heterologous systems, which limits their experimental utility.

Structural Analysis and Inhibitor Modeling of Bacterioferritin From Brucella abortus

open access: yesProteins: Structure, Function, and Bioinformatics, Volume 94, Issue 6, Page 1170-1181, June 2026.
ABSTRACT Iron homeostasis in various pathogenic bacteria is regulated by bacterioferritins (Bfr) which function to store Fe3+ and release Fe2+ as needed for metabolic processes. The Bfr structure consists of 18 kDa subunits in which dimer pairs bind a heme molecule and are assembled into a highly symmetrical 24‐meric spherical structure with an ...

Snapshots of Motion: A Novel Structural Intermediate Reveals Conserved Dynamics in Archaeal DNA Ligases

open access: yesProteins: Structure, Function, and Bioinformatics, Volume 94, Issue 6, Page 1245-1258, June 2026.
ABSTRACT We present the first x‐ray crystallographic structural evidence of an archaeal DNA ligase showing the AMP covalent adduct together with further cofactor hydrolysis, capturing a transient intermediary in the first step of the ligation reaction, triggered by the pyrophosphate hydrolysis.

Asymmetry of the Ferroelectric Phase Transition in BaTiO3

open access: yesAdvanced Materials, Volume 38, Issue 25, 4 May 2026.
Phase transitions are typically assumed to behave identically in forward and reverse. This work shows that in the ferroelectric material barium titanate this is not true: heating drives an abrupt, first‐order jump, while cooling gives a smooth, continuous change.

Polyoxometalates for Health, Electronics, Energy, and the Environment: Challenges, Opportunities, and Future Horizons

open access: yesChemistryEurope, Volume 4, Issue 5, May 2026.
Polyoxometalates (POMs), illustrated as lemon‐like cars racing along a winding road, symbolize the accelerating progress of POM research toward technological applications. Global research communities, recent advances, and emerging opportunities highlight how coordinated efforts drive the transition of POM science from molecular discovery to deployable ...
