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.

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

Mesh-free kinematic shakedown analysis of cohesive soils

International Journal of Geo-Engineering
A novel mesh-free solution is proposed for kinematic shakedown analysis of cohesive soils under repeating loads. For this purpose, the continuous velocity field in the mathematical expression of Koiter’s theorem is discretized by the Radial Point ...

Edged-based smoothed radial point interpolation method (ES-RPIM) for wave propagation problem

, 2021
Son yıllarda yapısal analizler mekanik tasarımlarda önemli bir rol üstlenmişlerdir. Tasarım hakkında fikir vermek amacıyla yapılan deneylerin yerini bilgisayar ortamında gerçekleşen analizler yer almıştır. Hazırlık süreci ve yapılan yatırımlar göz önüne alındığında bilgisayar ortamında yapılan analizlerin günümüzde daha fazla tercih edildiği ...
