Interactive segmentation of membrane and membrane‐mimic densities in cryo‐EM maps

Acta Crystallographica Section D, Volume 82, Issue 8, Page 848-861, August 2026.
SURFER performs automated segmentation of contextual membrane and membrane‐mimic density in cryo‐EM maps to enable robust separation of macromolecular signal from surrounding detergent or lipid–membrane features. It is conveniently distributed as a plugin for UCSF ChimeraX, allowing interactive application within standard map‐visualization workflows ...

PETIMOT: a novel framework for inferring protein motions from sparse data using SE(3)‐equivariant graph neural networks

Acta Crystallographica Section D, Volume 82, Issue 8, Page 862-885, August 2026.
We present a new formulation for protein flexibility and learn protein motions from sparse experimental data.Proteins move and deform to ensure their biological functions. Despite significant progress in protein structure prediction, approximating conformational ensembles under physiological conditions remains a fundamental open problem.

Crystal structure of endo‐β‐1,6‐galactanase from Streptomyces avermitilis

Acta Crystallographica Section D, Volume 82, Issue 8, Page 962-971, August 2026.
The crystal structure of S. avermitilis endo‐β‐1,6‐galactanase belonging to GH30 subfamily 5 reveals the first structural framework for endo‐β‐1,6‐galactanase. The β‐1,6‐galactobiose‐bound complex identifies the catalytic subsites and a distal secondary sugar‐binding site, providing insight into β‐1,6‐galactan recognition.Endo‐β‐1,6‐galactanases ...

Structural basis for a p21‐activated kinase 4 and nicotinamide phosphoribosyltransferase dual inhibitor

Acta Crystallographica Section D, Volume 82, Issue 8, Page 972-981, August 2026.
The 2‐aminopyridine moiety of KPT‐7523 binds p21‐activated kinase 4 and nicotinamide phosphoribosyltransferase, enabling a versatile design for multi‐target cancer therapy.Simultaneous inhibition of oncogenic signaling and metabolic pathways represents a promising approach for cancer therapy.

Central banks and information provided to the private sector

PSL Quarterly Review, 2012
This paper examines the information provided to the private sector by central banks. By using the principal component analysis, we investigated the variance of the procedural rules followed by nine major central banks about informationtreatments.

Protein Data Bank (PDB) Archive: a new architecture (beta) for scalable, PDBx/mmCIF‐based data distribution

Acta Crystallographica Section D, Volume 82, Issue 8, Page 982-989, August 2026.
wwPDB has extended PDB IDs to 12 characters with a prefix `pdb_' followed by eight alphanumeric characters in lower case (for example pdb_1000axyz). A beta version of the PDB Archive (https://files‐beta.wwpdb.org), with extended PDB IDs and an improved directory structure, is now available to help communities adopt extended PDB IDs and the PDBx/mmCIF ...
