Aminophospholipid glycation and its inhibitor screening system: a new role of pyridoxal 5′-phosphate as the inhibitor

open access: yesJournal of Lipid Research, 2006
Peroxidized phospholipid-mediated cytotoxity is involved in the pathophysiology of a number of diseases [i.e., the abnormal increase of phosphatidylcholine hydroperoxide (PCOOH) found in the plasma of type 2 diabetic patients]. The PCOOH accumulation may

Prevalence of low alkaline phosphatase activity in laboratory assessment: Is hypophosphatasia an underdiagnosed disease?

open access: yesOrphanet Journal of Rare Diseases, 2021
Background Tissue-nonspecific alkaline phosphatase (TNSALP) encoded by the ALPL gene is of particular importance for bone mineralization. Mutation in the ALPL gene can lead to persistent low ALP activity resulting in the rare disease Hypophosphatasia ...

Mechanistic perspective on the relationship between pyridoxal 5'-phosphate and inflammation.

open access: yesNutrition reviews, 2013
A variety of inflammatory disease conditions have been found to be associated with low levels of plasma pyridoxal 5'-phosphate (PLP), the active form of vitamin B6 , without any indication of a lower dietary intake of vitamin B6 , excessive catabolism of

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

open access: yeseLife
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 ...

Effect of blood contamination of cerebrospinal fluid on amino acids, biogenic amines, pterins and vitamins

open access: yesFluids and Barriers of the CNS, 2019
Background Cerebrospinal fluid (CSF) metabolomic investigations are a powerful tool for studying neurometabolic diseases. We aimed to assess the effect of CSF contamination with blood on the concentrations of selected biomarkers. Methods CSF samples were

Inhibition of O-acetylserine sulfhydrylase by fluoroalanine derivatives

open access: yesJournal of Enzyme Inhibition and Medicinal Chemistry, 2018
O-acetylserine sulfhydrylase (OASS) is the pyridoxal 5′-phosphate dependent enzyme that catalyses the formation of L-cysteine in bacteria and plants. Its inactivation is pursued as a strategy for the identification of novel antibiotics that, targeting ...

Late-onset drug-resistant epilepsy in pyridoxamine 5′-phosphate oxidase deficiency: a case report

open access: yesJournal of Medical Case Reports
Background Pyridoxamine 5′-phosphate oxidase deficiency is a rare inborn error of vitamin B6 metabolism that presents with drug-resistant epileptic seizures.

Reconstitution of the pyridoxal 5'-phosphate (PLP) dependent enzyme serine palmitoyltransferase (SPT) with pyridoxal reveals a crucial role for the phosphate during catalysis.

open access: yesChemical Communications, 2013
The pyridoxal 5'-phosphate (PLP)-dependent enzyme serine palmitoyltransferase (SPT) is required for de novo sphingolipid biosynthesis. A previous study revealed a novel and unexpected interaction between the hydroxyl group of the l-serine substrate and ...

Biomedical aspects of pyridoxal 5'-phosphate availability.

open access: yesFrontiers in Bioscience, 2012
The biologically active form of vitamin B6, pyridoxal 5'-phosphate (PLP), is a cofactor in over 160 enzyme activities involved in a number of metabolic pathways, including neurotransmitter synthesis and degradation.

Prediction of vitamin interacting residues in a vitamin binding protein using evolutionary information

open access: yesBMC Bioinformatics, 2013
Background The vitamins are important cofactors in various enzymatic-reactions. In past, many inhibitors have been designed against vitamin binding pockets in order to inhibit vitamin-protein interactions.
