Improvement of BsAPA Aspartic Protease Thermostability via Autocatalysis-Resistant Mutation

, 2019
An aspartic protease gene (Bsapa) was cloned from Bispora sp. MEY-1 and expressed in Pichia pastoris. The recombinant BsAPA showed maximal activity at pH 3.0 and 75 °C and remained stable at 70 °C and below, indicating the thermostable nature of BsAPA ...

The Impact of Iron‐Containing Particulate Matter on the Chemical Degradation of Cellulose Acetate in Collections

ChemPlusChem, Volume 91, Issue 11, November 2026.
Artificial particulate matter with high iron content and varied iron speciation accelerates cellulose acetate degradation, increasing chemical instability during aging. These findings identify a previously underexplored deterioration pathway and demonstrate that airborne pollutant composition can critically influence the preservation of historical ...

Assessment of Stoichiometric Autocatalysis across Element Groups

Autocatalysis has been proposed to play critical roles during abiogenesis. These proposals are at odds with a limited number of known examples of abiotic (and, in particular, inorganic) autocatalytic systems that might reasonably function in a prebiotic ...

Chronic Intermittent Hypoxia Aggravates the Pyroptosis of Renal Tubular Epithelial Cells Through Regulating Mitophagy‐Mediated NLRP3 Inflammasome Activation

Journal of Biochemical and Molecular Toxicology, Volume 40, Issue 11, November 2026.
Chronic intermittent hypoxia induced downregulation of PINK1, leading to deficient mitophagy, accumulation of damaged mitochondria and excessive ROS production, which further promoted the NLRP3 inflammasome complex assembly to trigger pyroptosis and the IL‐1β/IL‐18 release in renal tubular epithelial cells.

Sulfide capture of Co and Ni after peroxymonosulfate-assisted autocatalysis of EDTA complexes

Applied Catalysis O: Open
EDTA-enhanced Co and Ni extraction from low-grade ultramafic ore deposits can be promising if coupled to a concentration process for those elements. This study evaluates the efficiency of autocatalysis and decomplexation of metal-EDTA chelates using ...

3D Cellular Automata of Polymer Structural Response to Solvent Quality

Macromolecular Theory and Simulations, Volume 35, Issue 6, November 2026.
A minimal three‐dimensional cellular automaton captures solvent‐dependent polymer collapse, θ‐like scaling, swelling, and aggregation through simple local interaction rules. Radius‐of‐gyration scaling identifies the θ regime, while multichain simulations reveal that free chain ends and periodic self‐connection strongly govern structural reorganization,

Plasmepsins as Antimalarial Drug Targets—Then, Now, and the Future

Medicinal Research Reviews, Volume 46, Issue 6, Page 1574-1602, November 2026.
ABSTRACT Malaria is a devastating disease caused by Plasmodium parasites. Plasmodium parasites express ten cathepsin D‐like aspartyl proteases, called plasmepsins (PMs). These PMs have diverse roles fulfill diverse functions throughout the parasite's lifecycle, though several exhibit functional redundancies. Among them, PMV, PMIV, and PMX are essential

MONDE·T: A database and interactive webserver for non‐standard amino acids and peptide components in the PDB

Protein Science, Volume 35, Issue 11, November 2026.
Abstract Non‐standard amino acids (ncAAs) together with synthetic additions (like caps and linkers) are of wide interest for protein design and pharmaceutical optimization, as they can improve physicochemical properties and possibly reshape protein structure. Their inclusion in experimental structures has not been explored systematically.

Stability conditions of chemical networks in a linear framework

New Journal of Physics
Autocatalytic chemical reaction networks can collectively replicate or maintain their constituents despite degradation reactions only above a certain threshold, which we refer to as the decay threshold.

The Exceptional Challenges of Si‐Based Anodes and the Eternal Hunt for Electrolyte Additives: A Perspective on the Example of a Novel Dioxazaborole‐Based Molecule

Small Science, Volume 6, Issue 11, November 2026.
An ideal electrolyte additive, particularly for Si‐based anodes, should (i) promote the formation of an effective SEI, i.e., passivating and suppressing LiPF6/SiOx‐contact, (ii) minimize active Li loss (ALL) through efficient SEI formation, (iii) ideally enable “SEI‐waste” recovery and/or (iv) undergo sacrificial oxidation for prelithiation purposes ...
