Enzyme-Independent Interaction of Pyridoxal-5’-Phosphate with Cysteine [PDF]

, 2022
Pyridoxal-5′-phosphate (PLP), commonly known as Vitamin B6, is a versatile co-factor that assists in different types of enzymatic reactions. PLP has also been reported to react with substrates and catalyze some of these reactions independent of enzymes ...

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

Identification of YbhA as the pyridoxal 5'-phosphate (PLP) phosphatase in Escherichia coli: Importance of PLP homeostasis on the bacterial growth.

Journal of General and Applied Microbiology, 2018
The gene ybhA of Escherichia coli encodes a phosphatase that has an in vitro specificity to dephosphorylate pyridoxal 5'-phosphate (PLP or vitamin B6), a co-factor for aminotransferases and other enzymes. In this study, we found that excess pyridoxal (PL)

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 ...

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).
