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

open access: yesPLoS 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 ...

The endogenous production of hydrogen sulphide in intrauterine tissues [PDF]

open access: yes, 2009
Background: Hydrogen sulphide is a gas signalling molecule which is produced endogenously from L-cysteine via the enzymes cystathionine beta-synthase (CBS) and cystathionine gamma-lyase (CSE).

PLP Induced Inhibition of Thymidylate Synthase Activity in T Lymphocytes

open access: yesEuropean Journal of Inflammation, 2003
The present study was undertaken in order to examine whether pyridoxine may be used as an inhibitor of thymidylate synthase, and thus, as an antiproliferative agent.

Identification of atropine-and P2X1 receptor antagonist-reistant, neurogenic contractions of the urinary bladder [PDF]

open access: yes, 2007
Acetylcholine and ATP are excitatory cotransmitters in parasympathetic nerves. We used P2X1 receptor antagonists to further characterize the purinergic component of neurotransmission in isolated detrusor muscle of guinea pig urinary bladder.

Functional Characterization of the Eukaryotic Cysteine Desulfurase Nfs1p from Saccharomyces cerevisiae [PDF]

open access: yes, 2004
Previous studies have indicated that the essential protein Nfs1 performs a crucial role in cellular iron-sulfur (Fe/S) protein maturation. The protein is located predominantly in mitochondria, yet low amounts are present in cytosol and nucleus.

Pyridoxal Phosphate vs Pyridoxine for Intractable Seizures

open access: yesPediatric Neurology Briefs, 2005
The efficacy of pyridoxal phosphate (PLP) compared to pyridoxine (PN) in the control of idiopathic intractable epilepsy was studied in 94 children, aged 8 months to 15 years, at the National Taiwan University Hospital, Taipei, Taiwan.
