Structural basis for a filamentous morpheein model of human cystathionine beta-synthase

open access: yesNature Communications
Human cystathionine beta-synthase (CBS) is a vital enzyme that regulates sulfur amino acid metabolism, hydrogen sulfide production, and cellular redox balance.

Vitamin‐Responsive Disorders: From Molecular Basis to Clinical Presentation and Therapy

open access: yesJournal of Inherited Metabolic Disease, Volume 49, Issue 4, July 2026.
ABSTRACT Vitamin‐dependent cofactors are essential for numerous metabolic reactions, and defects affecting their uptake, conversion, utilisation, or regeneration constitute a heterogeneous group of inherited metabolic disorders (IMDs). Although dietary vitamin intake is sufficient to sustain coenzyme synthesis in healthy individuals, it is insufficient

Methionine Synthase Interacts With the Methionine Adenosyl‐Transferase MATα2 and the DNA Methyltransferase DNMT3b in the Nucleus

open access: yesJournal of Inherited Metabolic Disease, Volume 49, Issue 4, July 2026.
This study shows that methionine synthase (MS) interacts with MATα2, responsible for SAM production, and the methyltransferase DNMT3b in the nucleus. These results support the idea that spatial compartmentalization of one‐carbon metabolism could play a major role in regulating the epigenome.

Delay in Diagnosis of Classical Homocystinuria

open access: yesJIMD Reports, Volume 67, Issue 4, July 2026.
ABSTRACT Classical homocystinuria (HCU) is an autosomal recessive disorder of methionine metabolism with a wide spectrum of severity and clinical presentation. Timely diagnosis facilitates prompt initiation of treatment, which reduces complications. Our aim was to identify the nature of the first clinical manifestation and time to subsequent diagnosis ...

Comparative proteomics analysis of root and nodule mitochondria of soybean

open access: yesPlant, Cell &Environment, Volume 49, Issue 7, Page 3482-3499, July 2026.
Abstract Legumes perform symbiotic nitrogen fixation through rhizobial bacteroids housed in specialised root nodules. The biochemical process is energy‐intensive and consumes a huge carbon source to generate sufficient reducing power. To maintain the symbiosis, malate is supplied by legume nodules to bacteroids as their major carbon and energy source ...

Engineering of methionine-auxotroph Escherichia coli via parallel evolution of two enzymes from Corynebacterium glutamicum's direct-sulfurylation pathway enables its recovery in minimal medium

open access: yesMetabolic Engineering Communications
Methionine biosynthesis relies on the sequential catalysis of multiple enzymes. Escherichia coli, the main bacteria used in research and industry for protein production and engineering, utilizes the three-step trans-sulfurylation pathway catalyzed by L ...

Genetic attenuation of ALDH1A1 increases metastatic potential and aggressiveness in colorectal cancer

open access: yesMolecular Oncology, Volume 20, Issue 6, Page 1556-1590, June 2026.
Aldehyde dehydrogenase 1A1 (ALDH1A1) is a cancer stem cell marker in several malignancies. We established a novel epithelial cell line from rectal adenocarcinoma with unique overexpression of this enzyme. Genetic attenuation of ALDH1A1 led to increased invasive capacity and metastatic potential, the inhibition of proliferation activity, and ultimately ...

Protective effect of hydrogen sulfide on oxidative stress-induced neurodegenerative diseases

open access: yesNeural Regeneration Research, 2020
Hydrogen sulfide is an antioxidant molecule that has a wide range of biological effects against oxidative stress. Balanced oxidative stress is also vital for maintaining cellular function in biological system, where reactive oxygen species are the main ...

Muscarinic receptor drug trihexyphenidyl can alter growth of mesenchymal glioblastoma in vivo

open access: yesFrontiers in Pharmacology
Glioblastoma (GBM) is the most commonly occurring and most aggressive primary brain tumor. Transcriptomics-based tumor subtype classification has established the mesenchymal lineage of GBM (MES-GBM) as cancers with particular aggressive behavior and high

Short tandem repeats and methylation in the promoter region affect expression of cystathionine beta-synthase gene in the laying hen.

open access: yesGene, 2019
Homocysteine can be converted to cysteine via the transsulfuration pathway where cystathionine beta-synthase (CBS) is a rate-limiting enzyme. Homocysteine is thought to play a role in bone remodelling and strength. Previous results indicated that some of
