Direct polarographic determination of pyridoxal in the presence of pyridoxal-5-phosphate
Collection of Czechoslovak Chemical Communications, 1962The determination of pyridoxal in the presence of pyridoxal-5-phosphate may be1 based on the difference between the total wave-height obtained at pH about 9, where both substances give a diffusion-controlled wave and that obtained in acid media, where pyridoxal alone shows a kinetic current2.

Transport and Metabolism of Pyridoxal and Pyridoxal Phosphate in the Small Intestine of the Rat
The Journal of Nutrition, 1979The vascularly perfused small intestine of the rat was utilized to study the absorption and metabolism of pyridoxamine (PM) and pyridoxamine-5'-phosphate (PMP), independent of other tissues including erythrocytes. [3H]PM or [3H]PMP was administered intralumenally with or without the addition of unlabeled PM, or PMP or inorganic phosphate.

Neuroprotective Effects of Pyridoxal Phosphate and Pyridoxal against Ischemia in Monkeys
Nutritional Neuroscience, 2001Previously, in monkeys undergoing 20 min whole brain ischemia we demonstrated that the activated calpain-induced lysosomal disruption with the resultant leakage of cathepsins B and L, causes neuronal death in the cornu Ammonis (CA) 1 sector on day 5.

REGULATION AND FUNCTION OF PYRIDOXAL PHOSPHATE IN CNS
Neurochemistry International, 1981Pyridoxal phosphate and pyridoxamine phosphate, the catalytically active forms of vitamin B(6), influence brain function by participating at stages in metabolism of proteins, lipids, carbohydrates, other coenzymes and hormones. Vitamin B(6) participates in the metabolism of amino acids in the form of decarboxylation, transamination, deamination ...

Activation of DOPA decarboxylase by pyridoxal phosphate
Archives of Biochemistry and Biophysics, 1962Abstract DOPA decarboxylase from rat liver was purified by chromatography on DEAE-Sephadex. The purified enzyme decarboxylates o-tryosine, m-tyrosine, DOPA and 5-hydroxytryptophan at different rates. The pH optimum for all substrates was found to be 7.2. The enzyme has the characteristic absorption spectrum of other pyridoxal enzymes, thus indicating

Pyridoxal phosphate as a probe of reovirus transcriptase
Biochemistry, 1980The ribonucleoprotein core of reovirus is a multienzyme complex that transcribes messenger ribonucleic acid (mRNA) from double-stranded RNA templates. So far, the core has resisted attempts to disassemble it and identify the polypeptide species responsible for RNA polymerase activity. As an alternative approach, we tested pyridoxal 5-phosphate (PLP) as
