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 ...

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 ...

Pyridoxal 5′-Phosphate-dependent Catalytic Antibody [PDF]
Journal of Biological Chemistry, 1996 Cofactors might efficiently extend the catalytic potential of antibodies. Monoclonal antibodies against Nalpha-phosphopyridoxyl-L-lysine were screened for: 1) binding of 5'-phosphopyridoxyl amino acids, 2) binding of Schiff base of pyridoxal 5'-phosphate (PLP) and amino acids, the first intermediate of all PLP-dependent reactions, and 3) catalysis of ...

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.

Pyridoxal 5′-phosphate: electrophilic catalyst extraordinaire [PDF]
Current Opinion in Chemical Biology, 2009 Studies of nonenzymatic electrophilic catalysis of carbon deprotonation of glycine show that pyridoxal 5'-phosphate (PLP) strongly enhances the carbon acidity of alpha-amino acids, but that this is not the overriding mechanistic imperative for cofactor catalysis. Although the fully protonated PLP-glycine iminium ion adduct exhibits an extraordinary low
