Ketogenic diet-produced β-hydroxybutyric acid accumulates brain GABA and increases GABA/glutamate ratio to inhibit epilepsy

open access: yesCell Discovery
Ketogenic diet (KD) alleviates refractory epilepsy and reduces seizures in children. However, the metabolic/cell biologic mechanisms by which the KD exerts its antiepileptic efficacy remain elusive.

Covalently bound substrate at the regulatory site triggers allosteric enzyme activation [PDF]

open access: yes, 2008
The mechanism by which the enzyme pyruvate decarboxylase from yeast is activated allosterically has been elucidated. A total of seven three-dimensional structures of the enzyme, of enzyme variants or of enzyme complexes form two yeast species (three of ...

Branched chain aldehydes: production and breakdown pathways and relevance for flavour in foods [PDF]

open access: yes, 2009
Branched aldehydes, such as 2-methyl propanal and 2- and 3-methyl butanal, are important flavour compounds in many food products, both fermented and non-fermented (heat-treated) products. The production and degradation of these aldehydes from amino acids

ZZE-Configuration of chromophore ß-153 in C-phycocyanin from Mastigocladus laminosus [PDF]

open access: yes, 1987
The photochemistry of C-phycocyanin has been studied after denaturation in the dark. It shows an irreversible reaction which has characteristics of a Ζ,Ζ,Ε- to Z,Z,Z-isomerization of dihydrobilins. Its amplitude depends on the reaction conditions, with

Generation and characterization of a mouse line for monitoring translation in dopaminergic neurons [PDF]

open access: yes, 2017
We developed a mouse line targeting midbrain dopamine neurons for Translating Ribosome Affinity Purification(TRAP). Here, we briefly report on the basic characterization of this mouse line including confirmation of expression of the transgene in midbrain

Preclinical type 1 diabetes mellitus: a case from practice

open access: yesЛечащий Врач, 2021
At the preclinical stage diabetes mellitus can be diagnosed based on laboratory studies of blood glucose and detection of autoantibodies to insulin (IAA), islet cells (ICA), glutamate decarboxylase (GADA), tyrosine phosphatase (IA2A) and zinc transporter

Activating glutamate decarboxylase activity by removing the autoinhibitory domain leads to hyper γ-aminobutyric acid (GABA) accumulation in tomato fruit [PDF]

open access: yes, 2017
γ-Aminobutyric acid (GABA) is a ubiquitous non-protein amino acid with several health-promoting benefits. In many plants including tomato, GABA is synthesized via decarboxylation of glutamate in a reaction catalyzed by glutamate decarboxylase (GAD ...

The kynurenine pathway and the brain: challenges, controversies and promises [PDF]

open access: yes, 2017
Research on the neurobiology of the kynurenine pathway has suffered years of relative obscurity because tryptophan degradation, and its involvement in both physiology and major brain diseases, was viewed almost exclusively through the lens of the well ...
