Vitamin B6 Acquisition and Metabolism in Schistosoma mansoni

Frontiers in Immunology, 2021
Schistosomes are parasitic platyhelminths that currently infect >200 million people globally. The adult worms can live within the vasculature of their hosts for many years where they acquire all nutrients necessary for their survival and growth.

Metal binding to pyridoxal derivatives. An NMR study of the interaction of Eu(III) with pyridoxal phosphate and pyridoxamine phosphate [PDF]

, 1979
The solution conformations of pyridoxal-5′-phosphate and pyridoxamine-5′-phosphate have been investigated using Eu(III) as a nuclear magnetic resonance shift probe.

Cloning and Characterization of Pyridoxal Kinase from Geobacillus sp. H6a

Journal of Pure and Applied Microbiology, 2022
Pyridoxal kinase encoded by pdxK gene, is the important key enzyme in the salvage pathway of vitamin B6 biosynthesis. The enzyme catalyzes the phosphorylation of the 5′ alcohol groups of free form vitamin B6 into their 5′-phosphate forms that requires ...

Assembly of the eukaryotic PLP-synthase complex from plasmodium and activation of the Pdx1 enzyme

, 2012
Biosynthesis of vitamins is fundamental to malaria parasites. Plasmodia synthesize the active form of vitamin B6 (pyridoxal 5-phosphate, PLP) using a PLP synthase complex.

Synthesis of Cobalt(III) Complexes Derived from Pyridoxal: Structural Cleavage Evaluations and In Silico Calculations for Biological Targets

Inorganics
This study sought to investigate the synthesis of eight complexes constituted by a cobalt(III) (CoIII) metallic center coordinated to two units of iminic ligands LnC (n = 1–4, L1C–L4C), which are derivatives of pyridoxal hydrochloride and anilines with ...

An Antihemolytic Action of Pyridoxal.

Experimental Biology and Medicine, 1954
SummaryPretreatment of erythrocytes with 10 mM pyridoxal makes the cells subsequently more resistant to lysis by hypotonic solutions. Indoleacetic acid shows the same behavior to a smaller degree. These effects are attributed to a net loss of cell solutes in the form of potassium and chloride which the agents produce.

Effects of changing ions on the crystal design, non-covalent interactions, antimicrobial activity, and molecular docking of Cu(II) complexes with a pyridoxal-hydrazone ligand

Frontiers in Chemistry
The present work reports the influence of the presence of different ions (Cl−, Br−, NO3−, or SO42−) on the formation and proprieties of Cu(II) complexes with pyridoxal-benzoylhydrazone (PLBHZ).

Developmental and Epileptic Encephalopathy due to Biallelic Pathogenic Variants in PIGM

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective PIGM encodes a critical enzyme in the glycosylphosphatidylinositol (GPI)‐anchor biosynthesis pathway. While promoter‐region mutations in PIGM have been associated with a relatively mild phenotype characterized by portal vein thrombosis and absence seizures, recent evidence suggests that coding‐region mutations result in a more severe
