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

Simultaneous Determination of Underivatized Vitamin B1 and B6 in Whole Blood by Reversed Phase Ultra High Performance Liquid Chromatography Tandem Mass Spectrometry. [PDF]

PLoS ONE, 2015
Vitamin B1 (thiamine-diphosphate) and B6 (pyridoxal-5'phosphate) are micronutrients. Analysis of these micronutrients is important to diagnose potential deficiency which often occurs in elderly people due to malnutrition, in severe alcoholism and in ...

Protective role of vitamin B6 (PLP) against DNA damage in Drosophila models of type 2 diabetes [PDF]

, 2018
Growing evidence shows that improper intake of vitamin B6 increases cancer risk and several studies indicate that diabetic patients have a higher risk of developing tumors.

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.

NRF2 signalling in cytoprotection and metabolism

British Journal of Pharmacology, EarlyView., 2023
The KEAP1‐NRF2 system plays a central role in cytoprotection in defence mechanisms against oxidative stress. The KEAP1‐NRF2 system has been regarded as a sulfur‐utilizing cytoprotective mechanism, because KEAP1 serves as a biosensor for electrophiles by using its reactive thiols and NRF2 is a transcriptional factor regulating genes involved in sulfur ...

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 ...

Sugar and chromosome stability: Clastogenic effects of sugars in vitamin B6-deficient cells [PDF]

, 2014
Pyridoxal 5'-phosphate (PLP), the active form of vitamin B6, has been implicated in preventing human pathologies, such as diabetes and cancer. However, the mechanisms underlying the beneficial effects of PLP are still unclear. Using Drosophila as a model

Metabolic Engineering of the 5‐Aminolevulinate Biosynthetic Pathway in E. coli Improves Efficiency of Hemoprotein‐Based Biocatalysis

Angewandte Chemie, EarlyView.
We have engineered the heme biosynthetic pathway in E. coli to develop an efficient cofactor supplementation system for hemoproteins. Through the incorporation of the heterogeneous C4 pathway, the engineered cells significantly increase the expression levels of active holohemoproteins and enhance the efficiency of whole‐cell and lysate‐based ...
