A single residue affects the dynamics and shape of a tetrameric GH43 β‐1,4‐d‐xylosidase from Levilactobacillus brevis DSM1269

Protein Science, Volume 34, Issue 10, October 2025.
Abstract Lignocellulosic materials (e.g., straw and bran) are gaining interest as feedstocks for the manufacture of higher value products, recognizing xylooligosaccharides (XOS) as interesting prebiotic compounds, and putting enzymes converting xylooligosaccharides into focus.

Numerical Solution of System of N–Coupled Nonlinear Schrödinger Equations via Two Variants of the Meshless Local Petrov–Galerkin (MLPG) Method [PDF]

, 2014
In this paper three numerical techniques are proposed for solving the system of N-coupled nonlinear Schrödinger (CNLS) equations. Firstly, we obtain a time discrete scheme by approximating the first-order time derivative via the forward finite difference

A review of multiscale numerical modeling of rock mechanics and rock engineering

Deep Underground Science and Engineering, Volume 4, Issue 3, Page 382-405, September 2025.
Multiscale numerical methods of rock mechanics and rock engineering are reviewed, and the review results show that more attention should be paid to the development of an advanced constitutive model in addition to numerical techniques themselves. Abstract Rock is geometrically and mechanically multiscale in nature, and the traditional phenomenological ...

Meshfree Method–Based Modeling of Distributed Nanotransmission Line Phase Shifter for 5G Wireless Applications

International Journal of RF and Microwave Computer-Aided Engineering, Volume 2025, Issue 1, 2025.
The design and analysis of nanoelectromechanical systems (NEMSs) provide significant challenges due to the dominance of surface forces, quantum‐scale effects, and complex material properties, where classical electrostatics and continuum mechanics become inadequate.

The crystal structure of methanogen McrD, a methyl‐coenzyme M reductase‐associated protein

FEBS Open Bio, Volume 14, Issue 8, Page 1222-1229, August 2024.
Methyl‐coenzyme M reductase (MCR) is responsible for biological methanogenesis. McrD and MCR are conserved and colocated in methanogen genomes, with McrD protein able to form a complex with MCR. We present the high‐resolution McrD crystal structure of ferredoxin‐like domain monomers assembled into an α + β barrel‐like dimer, with conformational ...

Loop 6 and the β‐hairpin flap are structural hotspots that determine cofactor specificity in the FMN‐dependent family of ene‐reductases

The FEBS Journal, Volume 291, Issue 7, Page 1560-1574, April 2024.
Ene‐reductases (ERs) have different cofactor preferences—but why? We provide novel insights into the mystery behind cofactor preference in ERs using Solanum lycopersicum 12‐oxophytodienoate reductase 3 (SlOPR3) as a model enzyme. Our results, including crystallographic and computational data, indicate that NADPH and NADH exhibit different binding modes

Enhanced meshfree RPIM with NURBS basis function for analysis of irregular boundary domain [PDF]

, 2020
Radial Point Interpolation Method (RPIM) has become a powerful tool to numerical analysis due to its ability to provide a higher-order approximation function with the Kronecker delta property, by which the field nodes can be fitted exactly.
