Dietary Reference Values for vitamin B6

EFSA Journal, 2016
Following a request from the European Commission, the EFSA Panel on Dietetic Products, Nutrition and Allergies (NDA) derives Dietary Reference Values (DRVs) for vitamin B6. The Panel considers that plasma pyridoxal 5′‐phosphate (PLP) concentration is the

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.

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 ...

Synthesis of [13C3]-B6 Vitamers Labelled at Three Consecutive Positions Starting from [13C3]-Propionic Acid

Molecules, 2018
[13C3]-labelled vitamers (PN, PL and PM) of the B6 group were prepared starting from [13C3]-propionic acid. [13C3]-PN was synthesized in ten linear steps with an overall yield of 17%.

Pyridoxal 5'-phosphate is a slow tight binding inhibitor of E. coli pyridoxal kinase. [PDF]

PLoS ONE, 2012
Pyridoxal 5'-phosphate (PLP) is a cofactor for dozens of B(6) requiring enzymes. PLP reacts with apo-B(6) enzymes by forming an aldimine linkage with the ε-amino group of an active site lysine residue, thus yielding the catalytically active holo-B(6 ...

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.
