Pyridoxal phosphate-dependent neonatal epileptic encephalopathy

open access: yesArchives of Disease in Childhood - Fetal and Neonatal Edition, 2008
Pyridox(am)ine-5′-phosphate oxidase converts pyridoxine phosphate and pyridoxamine phosphate to pyridoxal phosphate, a cofactor in many metabolic reactions, including neurotransmitter synthesis. A family with a mutation in the pyridox(am)ine-5′-phosphate oxidase gene presenting with neonatal seizures unresponsive to pyridoxine and anticonvulsant ...

Chemical Composition, Amino Acids, Phenolic Profiles and Bioavailability of Minerals in Livingstone Potato (Plectranthus esculentus) as Affected by Different Processing Techniques

open access: yesFood Chemistry International, EarlyView.
Boiling retained the nutrients and polyphenol compounds in Plectranthus esculentus tubers better than frying or roasting. A bioavailability study showed that the phytates and oxalates in the tuber may not affect the bioavailabilities of calcium, zinc, or iron in Plectranthus esculentus tubers when eaten.

Do dietary patterns in older men influence change in homocysteine through folate fortification? The Normative Aging Study [PDF]

open access: yes
Objective We aimed to describe the difference in B-vitamin intake and in plasma B-vitamin and homocysteine concentrations before and after folic acid fortification, in relation to dietary patterns. Design The Normative Aging Study (NAS) is a longitudinal

Pyridoxal Phosphate Supplementation in Neuropediatric Disorders

open access: yesSeminars in Pediatric Neurology, 2016
Pyridoxal phosphate (PLP) is the active form of vitamin B6 and a cofactor in many enzyme reactions including neurotransmitter metabolism. PLP metabolism disturbances may mostly lead to refractory seizures. In this report, we review the main pathophysiological factors related with PLP deficiency and our experience in PLP treatment in pediatric patients ...

Infused Tiger Nut and Almond Nut Crunchy Snacks Enhanced the Nutritional Value and Antioxidant Activity in High‐Fat Diet Fed Rat

open access: yesFood Chemistry International, EarlyView.
Crunches were produced from formulations of almond nuts and tiger nuts (AN–TN) for the plausible management of commodity disease of obese condition. The produced AN–TN crunches showed high consumers acceptability, phenolic, and amylopectin contents. In addition, formulated percentages of AN–TN crunches when fed to high‐fat diet (HFD) fed rats led to ...

Current Insight into Human Ornithine Aminotransferase: A Review

open access: yesProteins: Structure, Function, and Bioinformatics, EarlyView.
ABSTRACT Human ornithine aminotransferase (hOAT) is a mitochondrial matrix pyridoxal‐5′‐phosphate enzyme (PLP) that catalyzes the reversible transfer of the δ‐amino group of L‐ornithine (L‐Orn) to α‐ketoglutarate (α‐KG) yielding glutamate‐5‐semialdehyde (GSA) and glutamate. GSA is prone to cyclize to Δ1‐pyrroline‐5‐carboxylate.

Crystal structure of the plant GABA aminotransferase AtGABA‐T from Arabidopsis thaliana

open access: yesActa Crystallographica Section F, EarlyView.
The crystal structure of A. thaliana γ‐aminobutyric acid aminotransferase (GABA‐T) reveals that plant GABA‐T belongs to the class III aminotransferase family and employs a C‐terminal arginine residue for γ‐aminobutyric acid recognition, in contrast to the N‐terminal arginine used by class II enzymes.γ‐Aminobutyric acid aminotransferase (GABA‐T) is a ...

Should PNPO Deficiency Be Treated In Utero? Clinical Findings From Prenatal Pyridoxine Therapy [PDF]

open access: yesJIMD Rep
ABSTRACT Pyridox(am)ine‐5′‐phosphate oxidase (PNPO) deficiency is characterized by early‐onset epileptic encephalopathy refractory to standard antiseizure medications. It is caused by variants in the PNPO gene, resulting in deficient PNPO enzyme activity, which normally converts pyridoxine‐5′‐phosphate and pyridoxamine‐5′‐phosphate (two vitamers of ...

A new branch of mammalian vitamin B6 metabolism: AKR1C‐mediated conversion of pyridoxal to pyridoxine and 4‐pyridoxolactone

open access: yesThe FEBS Journal, EarlyView.
Pyridoxal 5′‐phosphate (PLP) homeostasis relies on salvage enzymes, yet key metabolic branches remain undefined. We identify AKR1C isozymes as previously undescribed contributors that convert pyridoxal into pyridoxine or 4‐pyridoxolactone through reductase and dehydrogenase activities.
