Nodding syndrome in Tanzania may not be associated with circulating anti-NMDA-and anti-VGKC receptor antibodies or decreased pyridoxal phosphate serum levels-a pilot study.

African Health Sciences, 2014
BACKGROUND Nodding syndrome (NS) is a seemingly progressive epilepsy disorder of unknown underlying cause. We investigated association of pyridoxal-phosphate serum levels and occurrence of anti-neuronal antibodies against N-methyl-D-aspartate (NMDA ...

The physiological and pathological effects of sphingolipid metabolism and signaling in the central nervous system

Brain Pathology, EarlyView.
Sphingolipids are vital components of cell membranes. Metabolic disruptions of sphingolipids, including ceramide and sphingosine‐1‐phosphate, are linked to neurological disorders. This article summarizes the classification, structure, and metabolic processes of sphingolipids, and the physiological and pathological effects of sphingolipid metabolism and

Red cell aspartate aminotransferase saturation with oral pyridoxine intake

São Paulo Medical Journal
CONTEXT AND OBJECTIVE: The coenzyme of aspartate aminotransferase is pyridoxal phosphate, generated from fresh vegetables containing pyridoxine. Vitamin B6-responsive sideroblastic anemia, myelofibrosis and Peyronie’s syndrome respond to high pyridoxine ...

Effect of 3‐mercaptopyruvate sulfurtransferase (3‐MST) inhibitors on contractile responses in porcine coronary artery

British Journal of Pharmacology, EarlyView.
Background and Purpose Hydrogen sulphide (H2S) is synthesised endogenously through cystathionine β‐synthase (CBS), cystathionine γ‐lyase (CSE) and 3‐mercaptopyruvate sulfurtransferase (3‐MST). Although exogenous H2S is known to produce vasodilatation, the vascular effect of H2S produced through 3‐MST is unknown. In this study, we demonstrate the effect

Structural insights into the orthosteric inhibition of P2X receptors by non-ATP analog antagonists

eLife
P2X receptors are extracellular ATP-gated ion channels that form homo- or heterotrimers and consist of seven subtypes. They are expressed in various tissues, including neuronal and nonneuronal cells, and play critical roles in physiological processes ...

First‐in‐class inhibitors of SbnA reduce siderophore production in Staphylococcus aureus

The FEBS Journal, EarlyView.
The production of the iron‐chelating compound staphyloferrin B by the most invasive S. aureus strains is crucial for colonization, virulence, and survival in the host. Staphyloferrin B biosynthesis is carried out by eight enzymes, the Sbn system, that offer an appealing source of potential targets for the development of antimicrobials.

The disease‐linked R336C mutation in cystathionine β‐synthase disrupts communication with the PLP cofactor, yet maintains the enzyme's overall structural integrity

The FEBS Journal, EarlyView.
Cystathionine β‐synthase (CBS) is an essential enzyme involved in cysteine metabolism. The mutation R336C, associated with severe homocystinuria and of high incidence in Qatar, reduces its activity. Our research shows that this mutation does not destabilize the enzyme fold but subtly alters the tautomeric equilibrium of the PLP cofactor within the ...

Thiamin pyrimidine biosynthesis in Candida albicans : a remarkable reaction between histidine and pyridoxal phosphate.

Journal of the American Chemical Society, 2012
In Saccharomyces cerevisiae , thiamin pyrimidine is formed from histidine and pyridoxal phosphate (PLP). The origin of all of the pyrimidine atoms has been previously determined using labeling studies and suggests that the pyrimidine is formed using ...
