Genetic epilepsies with myoclonic seizures: Mechanisms and syndromes

open access: yesEpilepsia Open, EarlyView.
Abstract Genetic epilepsy with myoclonic seizures encompasses a heterogeneous spectrum of conditions, ranging from benign and self‐limiting forms to severe, progressive disorders. While their causes are diverse, a significant proportion stems from genetic abnormalities.

Crystal structure of human protein N-terminal glutamine amidohydrolase, an initial component of the N-end rule pathway. [PDF]

open access: yesPLoS ONE, 2014
The N-end rule states that half-life of protein is determined by their N-terminal amino acid residue. N-terminal glutamine amidohydrolase (Ntaq) converts N-terminal glutamine to glutamate by eliminating the amine group and plays an essential role in the ...

Mechanisms of metal-dependent non-redox decarboxylases from quantum chemical calculations

open access: yesComputational and Structural Biotechnology Journal, 2021
Quantum chemical calculations are today an extremely valuable tool for studying enzymatic reaction mechanisms. In this mini-review, we summarize our recent work on several metal-dependent decarboxylases, where we used the so-called cluster approach to ...

Methyl Jasmonate Seed Priming Mitigates the Defence‐Growth Trade‐Off and Tailors Plant Response to Specific Pests

open access: yesPlant, Cell &Environment, EarlyView.
ABSTRACT Seed defence priming is emerging as a novel, cost‐efficient and environmentally safe tool for pest management. It has been proposed as a means to uncouple the defence‐growth trade‐off in plants by enhancing defence responses with minimal fitness costs, but the mechanisms underlying this role remain elusive.

Studies on racemic triglycerides as urease enzyme inhibitors

open access: yesBangladesh Journal of Pharmacology
Amidohydrolase enzymes regulate key pathways, and their dysregulation is linked to infection, immune imbalance, and metabolic dysregulation in cancer. Current inhibitors have issues of cost, environmental persistence, and toxicity.

Structural Analysis of Saccharomyces cerevisiae Dihydroorotase Reveals Molecular Insights into the Tetramerization Mechanism

open access: yesMolecules, 2021
Dihydroorotase (DHOase), a dimetalloenzyme containing a carbamylated lysine within the active site, is a member of the cyclic amidohydrolase family, which also includes allantoinase (ALLase), dihydropyrimidinase (DHPase), hydantoinase, and imidase ...

Dali server update [PDF]

open access: yes, 2016
The Dali server (http://ekhidna2.biocenter.helsinki.fi/dali) is a network service for comparing protein structures in 3D. In favourable cases, comparing 3D structures may reveal biologically interesting similarities that are not detectable by comparing ...

Electrochemical Point‐of‐Care Test for Assessing Serum Paracetamol Concentration: Comparison With Traditional Methods and Detection of Concomitant Drugs

open access: yesBasic &Clinical Pharmacology &Toxicology, Volume 137, Issue 5, November 2025.
ABSTRACT Rapid serum paracetamol (acetaminophen) concentration measurement is essential in suspected intoxication, but centralized laboratory analyses often delay initiation of antidotal therapy. We studied the feasibility of a novel electrochemical single‐walled carbon nanotube/Nafion‐based point‐of‐care (POC) method in detecting paracetamol in 99 ...
